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.

11/40 is a fraction, and it is already in the simplest form. This is because they don't have any common factors, which means we can't use the GCF, greatest common factor, to divide each number. So 11/40 is already in simplest form.
So, 11/40ths is already in simplest form.
