IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 62 students attend a series of coaching classes before taking the test. Let u be the population mean IQ score that would occur if every student took the coaching classes. The classes are successful if u> 100. A test is made of the hypotheses Ho:=100 versus H :µ> 100. Consider three possible conclusions: (i) The classes are successful. (ii) The classes are not successful. (iii) The classes might not be successful. Part: 0/ 2 Part 1 of 2 Which of the three conclusions is best if Ho is not rejected? The best conclusion is (ii) (1) (i) (iii) Part: 1/ 2 Part 2 of 2 Assume that the classes are not successful. Is it possible to make a Type II error? Explain. (Choose one) , a type II error (Choose one) v possible. The classes are not successful when the null hypothesis is (Choose one) ▼
