In an all boys school, the heights of the student body are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. What is the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth?
The probability that a randomly selected student from the all-boys school will be shorter than 63 inches tall is approximately 0.9%.
To find the probability that a randomly selected student will be shorter than 63 inches tall, we need to use the standard normal distribution table or a statistical calculator.
Calculate the z-score for the value of 63 inches using the formula:
z = (X - μ) / σ
where X is the value (63 inches), μ is the mean (70 inches), and σ is the standard deviation (3 inches).
z = (63 - 70) / 3
z = -7 / 3
z = -2.3333
Now, we look up the area to the left of the z-score -2.3333 in the standard normal distribution table.
Using a standard normal distribution table, the cumulative probability for z = -2.33 (rounded to two decimal places) is approximately 0.009.
So, the probability that a randomly selected student will be shorter than 63 inches tall is approximately 0.009 or 0.9% (rounded to the nearest thousandth).

Answer:
The answer is 94.5
Step-by-step:
This is actually quite simple. Although, in order to do this you will need a calculator. First, you identify which trigonomic function you will use in order to find the value of x. for this problem you need to use the COS function. The equation for this is COS67= 67/x. Because you are trying to find x you would multiply each side by x. now the equation is xCOS67= 67. because you still can't find the value of x by doing this you will need to get x by itself. To get x by itself divide each side by COS67. the equation is now x= 94/ COS67. This is where the calculator comes in. On the calculator enter 94 divided by 67 then COS function. This gives you the measure of RS.

What is the standard deviation for the data given:
{12, 13, 29, 18, 61, 35, 21}
Answer:
15.866
Step-by-step explanation:
you would first find the mean of the data set by adding all the numbers together and dividing by the number of data points given (7 in this case).
12+13+29+18+61+35+21 = 189189/7 = 27you would then use the mean to solve for the standard deviation by using the equation, σ=√Σ(x-μ)²/N.
first, subtract the mean from all the data points
12-27=-15, 13-27=-14, 29-27=2, 18-27=-9, 61-27=34, 35-27=8, 21-27=-6then, square each calculated value from above
-15²=225, -14²=196, 2²=4, 9²=81, 34²=1156, 8²=64, 6²=36then, add the squared values together
225+196+4+81+1156+64+36 = 1762you would then divide 1762 by 7 (number of data values given orginally)
1762/7 = 251.714finally, take the square root of 251.714 to find the standard deviation
[tex]\sqrt{251.714} = 15.866[/tex]Simplify 12x6 y7 18 x3y5.

Absolute value of -8 = 8
Find the absolute values of the other numbers
The other numbers have to be less than 8 or else they are less than -8
Absolute value of 2.6 = 2.6 . 2.6<8
Absolute value of -10 = 10 . 10 >8 . not correct
Absolute value of -2 = 2 . 2<8
Absolute value of 4 = 4 . 4<8
Absolute value of 1/4 = 1/4 . 1/4<8
Absolute value of -8.5 = 8.5 . 8.5>8 . not correct
About Absolute Value:
Absolute value is the distance from 0 on the number line.
The number 5 is 5 units from 0
The number -5 is also 5 units from the 0, except from the opposite side
Absolute value states that negative numbers have a positive absolute value and a positive number has a positive absolute value.

Step-by-step explanation:
A recent taste test showed that 85% of people liked a new chicken sandwich recently added to a restaurant’s menu. The restaurant manager claimed that only 68% liked the new sandwich. To determine whether this sample supports the population proportion of 0.85, a simulation of 100 trials is run, each with a sample size of 30 and a point estimate of 0.85. The minimum sample proportion from the simulation was 0.66 and the maximum sample proportion from the simulation was 0.88.
a) Estimate the margin of error using the half the range method.
b) Use your margin of error to find the interval estimate.
c) Based on the computed interval estimate, is the restaurant manager’s claim that 68% of people liked the new sandwich valid? Explain your answer.
Answer:
a) The margin of error = 0.11
b) The interval estimate = (0.74, 0.96)
c) Not valid because 68% = 0.68 is less than the values in the interval estimate
Step-by-step explanation:
The statistical data from the population and the simulation are;
The percentage of the people that liked the new chicken sandwich = 85% = The population proportion
The percentage the restaurant manager claims liked the new sandwich = 68%
The number of trials of the simulation = 100 trials
The sample size of each trial = 30
The point estimate of each trial = 0.85
The minimum sample proportion = 0.66
The maximum sample proportion = 0.88
a) The confidence interval = (0.66, 0.88)
By the half the range method, the margin of error is given by half the width of the confidence interval
∴ The margin of error, MOE = (0.88 - 0.66)/2 = 0.11
b) The interval estimate are the expected range of numbers for a parameters
The interval estimate = The point estimate ± MOE
∴ The interval estimate = 0.85 ± 0.11 = (0.74, 0.96)
Given that the manager's claim of 68% is not within the interval estimate, the manager's claim is not valid based on the expected values for the people that liked the new sandwich found with the point estimate and the margin of error

The histogram shows the weights, in pounds, of checked luggage on a flight.
A graph shows weight of a bag (pounds) labeled 12 to 64 on the horizontal axis and number of bags on the vertical axis. 1 bag weighs 12 to 16 pounds. 4 bags weigh 16 to 20 pounds. 5 bags weigh 20 to 24 pounds. 6 bags weigh 24 to 28 pounds. 5 bags weigh 28 to 32 pounds. 4 bags weigh 32 to 36 pounds. 3 bags weigh 36 to 40 pounds. 1 bag weighs 40 to 44 pounds. 0 bags weigh 44 to 48 pounds. 1 bag weighs 48 to 52 pounds. 1 bag weighs 52 to 56 pounds. 1 bag weighs 56 to 60 pounds. 0 bags weigh 60 to 64 pounds.
The median weight of a checked bag is 27.5 pounds. How does the mean of the data most likely compare to the median?
The mean is most likely less than 27 pounds.
The mean is most likely exactly 27.5 pounds.
The mean is most likely about 28 pounds.
The mean is most likely more than 28 pounds.
Answer:
C, the mean is most likely about 28 lbs.
Step-by-step explanation:
The histogram shows the weights, in pounds, of checked luggage on a flight. The median weight of a checked bag is 27.5 pounds.
