What are the expressions?
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.

<em><u>solution</u></em>
<em><u>original </u></em><em><u>price </u></em><em><u>=</u></em><em><u> </u></em><em><u>final </u></em><em><u>price</u></em><em><u>+</u></em><em><u> </u></em><em><u>decrease</u></em><em><u> </u></em><em><u>percent</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>final </u></em><em><u>price</u></em>
original price = $90 +80% ×$90
original price = $90+80/100 ×$90
original price= $90+$72
original price= $162
