As per given , we have
n = 11
Since population standard deviation is missing, so we use t-test.
Critical t-value for 99% confidence :
[using two-tailed t-value table]
Confidence interval :
Hence, 99% confidence interval for the mean amount of time that students spend in the shower each day.=
Answer:
