Using the Central Limit Theorem, it is found that the mean of the sampling distribution of sample proportions is 0.37.
The <em>Central Limit Theorem</em> establishes that, for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportions has:
- Mean
.
- Standard error

For this problem, about 37% of high school seniors have vaped in the past year, hence
.
- Then, the mean of the sampling distribution of sample proportions is 0.37.

999/7 is just over 142
100/7 is just over 14
so there are (142 - 14) = 128 numbers that are multiples of 7, hence there are 999-99-128 = 772 numbers that are not multiples of 7.
Point slope form is an equation to graph lines.
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
