Scores on a certain IQ test are known to have a mean of 100. A random sample of 60 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. (Level of significant=0.01) Consider three possible conclusion: (i) The classes are successful. (ii) The classes are not successful. (iii) The classes might not be successful. Which of the three conclusion is best if the null hypothesis is not rejected. Explain why.
