(a). In each of the following research situations, state the type of statistical test that may be used to answer the research question. Give a brief reason for your answer. (i). The mean age of all 2000 students enrolled in the KCC weekend programme since the programme was started is equal to 35 years. The mean age of the 500 students who were enrolled in the programme during the 2020/2021 academic year is 40 years with standard deviation of 8 years. Is true that the 500 students enrolled in the programme during the 2020/2021 academic year are older than the population of all students enrolled in the programme? (ii). “As far as intelligence is concerned, women do not differ from the general population”. This is a claim by some researchers on gender issues. To test this claim, 100 women were sampled from the general population and their intelligence (IQ) measured. It was found that the mean IQ of the female sample was equal to 110. Assuming that the mean IQ in the general population is equal to 105 with a standard deviation of 10, how true is the claim by the researchers?
