To explain why it is not appropriate to perform a paired t test about the true mean difference (male minus female) in literacy rates in Islamic countries.
Explanation of Solution
To answer the question we must find out if the three conditions are satisfied or not, which is as:
Random: It is not satisfied because the samples included largely Muslim nations and thus the small nations were ignored which implies no random sample.
Independent: It is satisfied because the sample of
Normal: It is not satisfied because the sample is not large and the distribution is not approximately Normal.
Thus, all the conditions are not satisfied since the random condition and large sample is not satisfied and it is therefore not appropriate to determine the confidence interval for the population mean difference.
