Explain Step by step solution please.

Assume that both samples are independent simple random samples from populations having normal distributions. Answer only the following two parts and do not solve the entire hypothesis testing problem. 4) Use the summary statistics below to test the claim that the samples come from populations with different variances. Use a significance level of 0.05. Sample A Sample B n = 28 n =41 X* = 19.2 X2 = 23.7 S = 4.59 S = 5.58 a) Set up the null hypothesis and alternative hypothesis and indicate the claim under its corresponding hypothesis. b) Calculate the test statistic. Be sure to set up the equation
