. For the data man-hour data set given in Q1, a) Construct a 94% confidence interval for the mean man-hour (assume normality of the above man-hour data). b) At 1% level of significance test the hypothesis that Man-hour is more than 90 hours by critical value approach. c) Give an expression for p-value. On the basis of the t-table given in the Text, comment on the p-value. d) Compute the exact p-value by using Excel or any other statistical software. .
