Question 8 Зр The Generalized Aptitude Test, G.A.T., is a brand new untried measure of general reasoning. The scores on this type of test usually have a normal distribution but with u an ounknown. An independent random sample of size n = 64 yields the following statistics, SM = 319.4 and Sx = 83.7. The designers of the test intended the mean value to be 350. Find out if the results support the hypothesis that the mean value is less...

Question 3 4 pts Acme Products manufactures widgets. It has two machines which produce widgets. It is desirable that both machines produce widgets of the same dimensions. At regular time intervals Acme's quality control tests the widgets from both machines. The last test produced the following results. In this context sM is the sample mean. SM1 = 5.61 S1 = 1.07 n1 = 100 SM2 = 5.89 S2 = 1.26 n2 = 100 Do the machines produce different sized widgets?...

Question 33 1 pts If the significance level for a hypothesis test is 0.01 and the p-value for the test ends up being 0.0034, after forming the appropriate conclusion based on the p-value, which possible error could have be committed, type I or type II. Since we did not reject the null, we might have committed a type one error. O Since we did not reject the null, we might have committed a type two error. Since...
