Answer: (6.304, 6.696)
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where = Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Let x denotes the number of hours slept by UCF students.
Given :
n= 400
Two-tailed critical value for 95% confidence interval =
Then, the 95%confidence interval for the true number of hours slept by UCF students will be :-
Hence, the 95% confidence interval for the true number of hours slept by UCF students : (6.304, 6.696)
