A random sample of 39 students attend a series of coaching classes before taking the test. Letu be the population mean IQ score that would occur if every student took the coaching classes, The classes are successful,100. A test is made of the hypothesesHo: -100 versus H i: > 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 out of 2 Which of the three conclusions is best if Ho is rejected? The correct conclusion is (select). NEXI Ass Time 0

Explanation / Answer

When we do a hypothesis test we do it at a particular confidence interval, rejecting the null hypothesis here would indicate that we have sufficient evidence that the class is successful but as we are doing it with a particular confidence interval, there is always a chance of a type I error which is the incorrect rejection of the null hypothesis. Therefore we cannot say anything with certainty. Therefore the correct conclusion here would be given as:

The classes might not be successful.
