Answer:
Hence the 90% confidence interval estimate of the population mean is
Step-by-step explanation:
Given that,
Point estimate = sample mean = = 88.34
sample standard deviation = s = 19.22
sample size = n = 14
Degrees of freedom = df = n - 1 = 13
Critical value = df = 1.771
Margin of error
Margin of error = E = 9.10
The 90% confidence interval estimate of the population mean is,
