A large world-wide internet companywas interested in equal rights for its employees with respect to the number of hours of paid leave, ortime off. The argument from employees without children designated as Group A is that they are not given 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 E employees and the company wondered if it should also offer more hours of paid leave to employees in Group A. After accumulating the leave reports from 2020. detailing the annual amount of paid leave taken by a random sample of size 25 from Group A and a random sample of size 20 from Group 3' a condence interval was com: mean 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 thatthe populations have equal variances. Question 4 Choose the best answer below concerning the condence interval for the difference between the annual amount of paid leave by Group A minus the annual amount of paid leave by Group E.
