Select two data sets and decide which hypothesis testing discussed in class should be used and matched with your data set. Construct a 99% confidence interval for a mean difference and Test at a 1% significance level. Use both the P-value and the critical-value approaches to make this test and interpret your results. If you cannot reject the null hypothesis, please adjust to 5% or 10% significance level. East Asia and Pacific Europe and Central Asia Difference 9.67104 7.51427 2.15677...
