Information for question :A large world wide Internet company was interested in equal rights for its employees with respect to the number of hours of paid leave, or time off. The argument from employees without children designated as group A is that they are not given the same allowances, and paid leave as employees with children designated as Group B. In 2020, this company allowed up to 40 extra hours of paid leave to Group B employees and the company wondered if it should also offer more hours of paid leave to the employees in Group A. After accumulating the leave reports from 2020, detailing the annual amount of pay leave taken by a random sample size 25 from Group A in a random sample size of 20 from Group B, confidence interval, was computed for the main difference in the annual amount of paid leave by Group A minus the annual amount of paid leave by Group B. Assume that independent random samples were taken from populations that were normally distributed, and that the populations have equal variances.

Question 5 1 pts Assuming that the confidence coefficient is 98%, then choose from the following concerning the z- value or t-value that would be used in the interval. O 1.96 O 2.24 O 2.42 O 2.10
