Answer:
1341.2<x<1458.8
Step-by-step explanation:
Given
sample size n = 64
standard deviation = 240
average mean = 1400
z score at 95% CI = 1.96
Required
confidence interval
Confidence interval = xbar ± (z*s/√n)
CI = 1400 ± (1.96*240/√64)
CI = 1400 ± (1.96*240/8)
CI = 1400 ± (1.96*30)
CI = 1400 ± 58.8
CI = (1400-58.8, 1400+58.8)
CI = (1341.2, 1458.8)
Hence the confidence interval for the population is 1341.2<x<1458.8
