A random sample of 38 middle management employees was taken from a database of a large service company. The employees were grouped by gender.

Following a discussion with an executive in the human resources department who stated that the salary of female managers is lower than that of male managers, we want to compare the average annual salary according to the gender of the employee.

Using a significance level of 1%, we obtain the following Excel report: The following two values are the descriptive thresholds for a two-tailed and a one-tailed right-hand test: 0.009795 and 0.019591.

Which statement is correct?

It is assumed that the data obtained for each group of employees are normally distributed with unknown variances but assumed to equal a common variance s2

Options: 0.009795 is the descriptive threshold for a two-tailed test and we do not reject Ho.

0.019591 is the descriptive threshold for a one-tailed right-hand test and we reject Ho.

0.009795 is the descriptive threshold for a one-sided right-hand test and we reject Ho.

0.019591 is the descriptive threshold for a one-tailed test on the right and we do not reject Ho.

0.019591 is the descriptive threshold for a two-tailed test and we reject Ho.

0.009795 is the descriptive threshold for a two-tailed test and we reject Ho.
