ra1l [238]

Answer:

The mean of sampling distribution of the proportion of the students who prefer later start times for school

μₓ = p = 0.63

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given sample size 'n' =200

given data Of the 200 students surveyed at the local high school, 126 say that they prefer earlier start times for school

sample proportion

$p = \frac{x}{n} = \frac{126}{200} = 0.63$

The mean of sampling distribution of the proportion of the students who prefer later start times for school

μₓ = p = 0.63

Standard deviation of the proportion

$S.D = \sqrt{\frac{p(1-p)}{n} } = \sqrt{\frac{0.63(1-0.63)}{200} } = 0.034$
