A researcher reports that 80% of high school seniors would pass a driving test, but only 45% of high school freshmen would pass the same driving test. Assume that the researcher’s claim is true. Suppose a driving test is given to a random sample of 90 high school seniors and a separate random sample of 85 high school freshmen. Let and be the sample proportions of seniors and freshmen, respectively, who pass the test. What are the shape and mean of the sampling distribution of ? skewed left with mean –0.35 skewed right with mean 0.625 exactly Normal with mean 0.35 approximately Normal with mean 0.35 approximately Normal with mean 0.625
Answer:
approximately Normal with mean 0.35
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
A researcher reports that 80% of high school seniors would pass a driving test, but only 45% of high school freshmen would pass the same driving test.
This means that [tex]p_1 = 0.8, p_2 = 0.45[/tex]
Subtraction of Variable 1 by Variable 2:
By the Central Limit Theorem, the shape will be approximately normal.
The mean is the subtraction of the means of each proportion. So
[tex]p = p_1 - p_2 = 0.8 - 0.45 = 0.35[/tex]
So the correct answer is given by:
approximately Normal with mean 0.35

Answer:
∠2 = 19°
Step-by-step explanation:
Angles that are equal to 161° are vertical and corresponding angles: 1, 4, 5.
Angles that are equal to the supplement of 161° are the remaining angles: 2, 3, 6, 7.
Angle 2 is the supplement of 161°:
∠2 = 180° -161°
∠2 = 19°

Ted can change an advertisement on a billboard in 5hr. Marie can do the same job in 2hr. How long would it take them if they worked together? Write your answer as a fraction or mixed number, if necessary.
Answer:
Working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
Step-by-step explanation:
Given that Ted can change an advertisement on a billboard in 5 hours, while Marie can do the same job in 2 hours, to determine how long it would take them if they worked together the following calculation must be performed:
Ted 1/5 in 1 hour
Marie 1/2 in 1 hour
1/5 + 1/2 = X
5X + 2X = 10
7X = 10
X = 10/7
X = 1 3/7
60/7 x 3 = 25.71
60 x 0.71 = 42.6
So, working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.

1. Jada made 6 cups of blueberry jam and divided the jam equally among 4 containers, How much jam
went in each container?
answer
6 cups
=?
2. Jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the vasche booka
answer
75 pages
Ad speaker notes
Answer:
1: 1.5 Jam Went Into Each Cup
2: 125 pages
Step-by-step explanation:
1
In order to find our answer we first have to divide 6/4, we then get 1.5 jam, finally we check our answer 1.5 x 4 = 6, Thus that is our answer
In order to find the answer to this equationFirst, we divide 6 and 4Then, we get our answer 1.5Lastly, in order to make sure I am correct, multiply 1.5 x 4 and we get 6, thus 1.5 is correct2
If Jada has read 3/5 of a book, and that equals 75, then we divide 75 by 3 giving us 25, then in order to find the answer we have to multiply 25 by 5, thus 125 is our answer
In order to find the answer to this equationFirst, we divide 75 by 3Then, we get 25Lastly, we multiply 25 by 5 and we get 125, thus that is our final answerCan you help me please here is the image

Which of these is an exponential parent function?
A. f(x) = x
B. f(x) = x
C. f(x) = 2x
D. f(x) = 1x1
SMIT
Option B is correct, f(x) = 2ˣ is an exponential parent function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The exponential parent function is of the form:
f(x) = aˣ
where a is a positive constant (the base of the exponential function).
Among the given options, the exponential parent function is,
⇒ f(x) = 2ˣ,
Because it has the form of an exponential function, where the base is 2.
f(x) = x is a linear function, not an exponential function.
f(x) = |x| is an absolute value function, not an exponential function.
f(x) = x² is a quadratic function, not an exponential function.
Hence, f(x) = 2ˣ is an exponential parent function, Option B is correct.

Write each absolute value in a box to show the order from least to greatest.
|11| |–8| |–2| |5| |–12|
Answer:
|–2| |5| |–8| |11| |–12|
Answer:
|-2|,|5|,|-8|,|11|,|-12|
Step-by-step explanation:
This is the order because |-2| in absolute value is positive 2 and |11| in absolute value is still positive because you don't change the sign unless the ll was negative in absolute value.
Question 6 of 25
Today Charlie put a ring on layaway by making a down payment of $85 and
agreeing to pay $18 per month, starting next month, for 21 months. When will
Charlie receive the ring?
O A. In 21 months
O B. In 1 month
O C. Today
OD. In 18 months
Charlie will receive the ring in 21 months.
What does layaway mean?It is a method of buying something in which a person can make a downpayment to buy something at a store and the store holds the item on their behalf until the last payment is done after which they gain possession of it.
Charlie has put in a ring on layaway. This means that he will only receive the ring in 21 months after he has finished paying all the installments. He will not gain possession of the ring right away after making the downpayment of $85.
Thus, we have found that Charlie will receive the ring in 21 months. The correct answer is option A.
