(a) State the point estimates for the
population mean and standard deviation.
(b) Calculate the 95% confidence interval for
the population mean. Show
all the steps required.
(c) Determine the conclusion for your case
above.
(d) Suggest how to improve the reliability and
precision of the confidence interval calculated. Calculate the
minimum sample size to reduce the width of confidence interval
calculated by half.
