Explanation / Answer

90% confidence interval

Standard error of the mean = SEM = S/N = 4.127

t(, N-1) = 1.645

Confidence interval = m +/- (t(, N-1)*SEM)

Mean = 1575

Lower bound: 1568.21

Upper bound: 1581.79

99% confidence interval

Standard error of the mean = SEM = S/N = 4.127

t(, N-1) = 2.577

Confidence interval = m +/- (t(, N-1)*SEM)

Mean = 1575

Lower bound: 1564.36

Upper bound: 1585.64
