Perform the required hypothesis test for two population standard deviations. Assume that independent samples havebeen randomly selected from the two populations and that the variable under consideration is normally distributed onboth populations. Use the critical-value approach.
-Test scores for random samples of students from two different schools were recorded. The summary statistics are given below. Do the data provide sufficient evidence to conclude that variation in test scores differs between students from school A and students from school B? Use a significance level of 0.10.
