IQ: Scores on a certain IQ test are known to have a mean of 100. A random sample of 39 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:u=100 versus H >100. Consider three possible conclusions: (i) The classes are successful. (ii) The classes are not successful. (i) 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) |(i) |(i) (iii) Part: 1/2 Part 2 of 2 Assume that the classes are not successful.
