3. Heights of 1-year-old girls are Normally distributed, with mean 30 inches and standard deviation of 1.2 inches. A company claims that taking 500 mg of vitamin C makes girls taller. In a random sample of 100 baby girls who were given 500 mg vitamin C daily from birth to 1 year, the mean height was 30.1 inches. Is this evidence for the company’s claim? Assume the standard deviation remains the same. To make this determination, calculate and interpret the p-value for the appropriate test.
Answer:
The p- value is [tex]p-value = 0.2033[/tex]
Its interpretation is
As [tex]p-value > \alpha[/tex]
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to support the company claims at a level of sign9ificance of 0.05
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 30 \ inches[/tex]
The standard deviation is [tex]\sigma = 1.2 \ inches[/tex]
The sample size is n = 100
The sample mean is [tex]\= x = 30.1[/tex]
Let assume the level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu \le 30[/tex]
The alternative is [tex]H_a : \mu > 30[/tex]
Generally the test test is mathematically represented as
[tex]z = \frac{\= x- \mu }{\frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{30.1- 30 }{\frac{1.2}{\sqrt{100} } }[/tex]
=> [tex]z = 0.83[/tex]
Generally from the z-table the probability of (Z > 0.83 ) is
[tex]p-value = 0.2033[/tex]
From the value obtained we see that [tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to support the company claims at a level of sign9ificance of 0.05

Write the set that represents the set of people surveyed who subscribe to at least one of the two news sources given.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The set of people in a certain community who were asked if they subscribe to an information source is U
The set that subscribes to The Daily Informer is D
The set that subscribe to News Magazine is N
Here the universal set is U
Now the word at least here means that the person can subscribe to one or two of the information source , but the person cannot subscribe none of the information source
Now to get the set that represents the set of people surveyed who subscribe to at least one of the two news sources , we need to carry out a union operation on the sets representing the two news source , this can be mathematically represented as
[tex]L = N \ u \ D[/tex]
So the sets that will contain all the people in the community that subscribe to at least one of the news source is L
divide and answer in simplest form: 1/3 divided by 5
Answer:
1/15
Step-by-step explanation:
1. You can divide 1/3 by 5 by changing the division symbol to its reciprocal, multiplication, and also divide by the reciprocal of the number after the symbol, 5. The reciprocal of 5 is 1/5.
2. Now you can do 1/3 multiplied by 1/5. Multiply the numerators by the denominators. The numerators are 1 and 1, so you multiply 1 by 1 which equals 1. Now you multiply the denominators, 3 and 5, which is equal to 15. If the numerator is now 1, and the denominator is 15, the new fraction is 1/15, getting you to your answer

Step-by-step explanation:
5. Ed, an employee of the Natural Color Company, suffered from a rare disease that was very expensive to treat. The local media ran several stories about Ed’s problems, and the family created a website that generated more than $10,000 in gifts from individuals to help pay the medical bills. Ed’s employer provided hospital and medical insurance for its employees, but the policy did not cover Ed’s illness. When it became apparent that Ed could not pay all of his medical expenses, the hospital canceled the $25,000 Ed owed at the time of his death. After Ed’s death, his former employer paid Ed’s widow $12,000 in "her time of need." Ed’s widow also collected $50,000 on a group term life insurance policy paid for by Ed’s employer. What are Ed’s and his widow’s gross income?
Answer:
$0
Step-by-step explanation:
The $10,000 that Ed's family received as gifts from individuals to help them pay the hospital bill are not included as part of their gross income.
Generally debt cancellations are taxable, except when they are made out of "detached and disinterested generosity", i.e. debt is cancelled for humane reasons and not business reasons. I believe that the $25,000 debt that was cancelled by the hospital fits into the definition of disinterested generosity, therefore, the $25,000 are considered a gift and are not taxable.
Under section 102, money given by an employer to an employee's widow may be considered a gift and is not taxable. If the payment is made due to a special circumstance and not in recognition of previous work done, then it is a gift. I also believe that the family can argue that this money is a gift since Ed died of a rare disease that left them almost bankrupt.
Life insurance proceeds are not taxable.

Suppose x and y give the populations of two different cities where x >y and y > 0. Compare the expressions and select which of the given pair is greater. X/ x +y (select) x+y /X
Answer:
(x + y)/x is greater than x/(x + y)
Step-by-step explanation:
Given.
x > y
y > 0
Required
Which is greater?
x/(x + y) or (x + y)/x
Since x is greater than y & y > 0
Then definitely,
x + y > x
By the above analysis:
(x + y)/x is an improper fraction because the numerator (x + y) is greater than the denominator (x)
While
x/(x + y) is a proper fraction because the numerator (x) is lesser than the denominator.
All improper fractions are greater than all proper fractions,
Hence:
(x + y)/x is greater than x/(x + y)
To further explain this:
Take
x = 3 and y = 2
x/(x + y) = 3/(3 + 2) = 3/5 = 0.6
(x + y)/x = (3 + 2)/3 = 5/3 = 1.67
See that (x + y)/x is greater than x/(x + y)
And this is so for all values of x and y
Where x > y and y > 0

how do u write 2.25 in standard form?
9514 1404 393
Answer:
2.25
Step-by-step explanation:
The number 2.25 is already in standard form.
___
In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.
In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.
2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)

(4x-3y)(4x+3y)
Step-by-step explanation:
This is a difference of squares equation. As it says, ([tex]x^{2} -y^2[/tex]) is equal to (x-y)(x+y)
Simply apply the formula to your numbers, [tex]16x^{2} -9y^2[/tex].
It gives the hint of [tex]16x^{2}[/tex] is equal to (4x)^2. and, 9y^2 is equal to (3y)^2, since if you square 4x and 9y, they get 16x^2 and 9y^2 respectively.

The Acme Battery Company has developed a new cell phone battery. On average, the battery lasts 60 minutes on a single charge. The standard deviation is 4 minutes. Suppose the manufacturing department runs a quality control test. They randomly select 7 batteries. The standard deviation of the selected batteries is 6 minutes. a. What would be the chi-square statistic represented by this test? b. What are the degrees of freedom for the chi-square statistic? c. Suppose they repeated the test with a new random sample of 7 batteries. What is the probability that the standard deviation in the new test would be greater than 6 minutes? (Use the applet)
Answer:
X² = 13.5
Degree of freedom = 6
0.04
Step-by-step explanation:
Give the following :
Number of samples (n) = 7
Population standard deviation (σ) =.4 minutes
Sample standard deviation (s) = 6
Mean battery life = 60 minutes
A) Chisquare (X²) :
X² = ((n - 1) * s²) / σ²
X² = ((7 - 1) * 6²) / 4²
X² = (6 * 6²) / 4²
X² = (6 * 36) / 16
X² = 216 / 16
X² = 13.5
B.) The degree of freedom:
degree of freedom = n - 1
Degree of freedom = 7 - 1 = 6
C.) using a chisquare distribution calculator :
With degree of freedom (df) = 6
X² = 13.5
Hence,
P(X² > 13.5) = 0.04 ( from calculator)
Suppose you have 3 quizzes and want an average of 7 points. List at least five ways this average can be accomplished. keep in mind that each score can be no more than 10 points.
Answer:
4,9,8 = 4+9+8 = 21
9,9,3 = 9+9+3 = 21
6,7,8 = 6+7+8 = 21
8,8,5 = 8+8+5 = 21
5,7,9 = 5+7+9 = 21
Step-by-step explanation:
The question says you get 7 points per quiz out of 3 quizzes.
7+7+7 = 21
Now that we know that we need a total score of 21, we therefore need to distribute it among the three quizzes.
Remember;
None of these scores are to be higher than 10. We need to add up scores below 10.
4,9,8 = 4+9+8 = 21
9,9,3 = 9+9+3 = 21
6,7,8 = 6+7+8 = 21
8,8,5 = 8+8+5 = 21
5,7,9 = 5+7+9 = 21
All of these gives 7 as average.
