use an x^2 test to test the clain o^2 = 0.53 at the a=0.10 signifigance level using sample statistics s^2 = 0.495 and n=18.  assume the population is normally distributed

A data set from a study that examined the effect of a specific diet on blood pressure is below. Participants (n = 72) were randomly assigned either to a group that was put on the diet (Diet = Present) or to a group that was not put on the diet (Diet = Absent), and researchers wanted to know whether the diet had a significant impact on blood pressure. Evaluate the homogeneity of variance assumption for the test and report the results (i.e., is the assumption reasonable for this analysis/data set?).

At a .05 significance level with a sample size of 19, find the critical value for the correlation coefficient. (Just enter the positive value rounded to three places.)
