Using sample 3, test the claim that Ho: µ = 1.2Xsample1 versus H1: µ> 1.2Xsample1; where X sample i is the average of sample 1 (problem 1). Assume o² is

unknown and a=0.05. 2- Using sample 3, test the claim that Ho:o² = 1.2S²,1.2S?sample2 versus H:0² ±is the variance of sample 2 (problem 2). Use a=0.05 - One of the disadvantages of the test of the hypothesis is that the final decisioncannot be said to be completely correct evidence or explained with full certainty.Provide a clear explanation - How do you find the Test of Hypothesis is different from the Interval Estimation?Use your words and provide a general explanation.
