a. Suppose you want to determine whether the average values for populations 1 and 2 are different, and you randomly gather the following data.,Test your conjecture, using a probability of committing a Type I error of .01. Assume the population variances are the same and x is normally distributed in the populations.,b. Use these data to construct a 98% confidence interval for the difference in the two populationmeans.
