IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 51 students attend a series of coaching classes before taking the test. Let µ be the population mean IQ score that would occur if every student took the coaching classes. The classes are successful if µ>100. A test is made of the hypotheses Ho:H=100 versus H, :µ>100. Consider three possible conclusions: (i) The classes are successful. (ii) The classes are not successful. (ii The classes might not be successful. Part 1 of 2 Which of the three conclusions is best if H, is not rejected? The best conclusion is (Choose one) ▼ Part 2 of 2 Assume that the classes are not successful. Is it possible to make a Type II error? Explain. a type II error (Choose one) (Choose one) hypothesis is (Choose one) ▼ possible. The classes are not successful when the null
