Calculate a 99% confidence interval for the mean time taken to repair the automobileby the (i) certified mechanic and (ii) the trainee mechanic. b. Test the hypothesis that the two mean times for both mechanics are equal. Use the 5%level of significance. Subsequently, it was learnt that the times for the trainee were incorrecly recorded andthat each of the values above is 30 minutes too small. What, if any, difference doesthis make to the results of the test done in part (b)?
