Answer:
The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.133, 0.161).
√2π / √5 (expand the expression)
√2π / √5 x √5 / √5 (multiply the fractions)
√2π√5 / √5/√5 (calculate and multiply)
solution is √10π/5 so 1.98 round it to the nearest 10 and it'll be 2 so the answer is D
