uestion 2: n international private school called IWB has two branches in the GCC countries, one Oman and another in Kuwait. IWB manager believes that there is no difference in the dent enrollment rate for their branch in Oman and the branch in Kuwait. A random mple of 25 students from Oman's branch was selected. The student enrollment rate in e sample found to be 24%. Another random sample of 30 students from the branch in uwait showed an enrolment rate of 27%. a. Find a point estimate for the difference between the population proportions for the two countries (Oman and Kuwait). b. Find a point estimate of the standard deviation for the difference between the population proportions for the two countries. c. Construct a 99% confidence interval for the difference between the population proportions for the two countries. d. State the null and alternative hypotheses. e. Test the hypothesis stated in Part d at the 1% significance level. f. What do you conclude? nswer:
