Question

Q1:A certain dimension is measured on four successive items coming off
a production line. This sample gives x = 2.384 and s = 0.048.
a) On the basis of this sample, what is the 95% confidence interval for the

population mean?
b) If instead of estimating the standard deviation from a sample, we knew
the true standard deviation was 0.048, what then would be the 95%
confidence interval for the population mean?
