A company is considering the introduction of a new training program aimed at improving the productivity of its customer support team. The number of customer inquiries resolved per hour by a sample of 4 support agents before and after completing the training program is recorded. Using a significance level of \alpha = 0.05, test whether the training program has resulted in a significant increase in the mean number of customer inquiries resolved per hour by the support team. resolved cases: customer agent 1: before 6, after 8. customer agent 2: before 10, after 10. customer agent 3: before 8, after 10. customer agent 4: before 11, after 12. state null and alternative hypothesis, compute the test statistic, p value, and provice a 95% confidence interval for the difference of number of inquries resolved after the training program
