IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 63 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 Hoμ= 100 versus H₁ 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 rejected? The best conclusion is (i) Part: 1/2 Part 2 of 2 ☑ Assume that the classes are not successful. Is it possible to make a Type II error? Explain. No true a type II error is not possible. The classes are not successful when the null hypothesis is ☑
