Question

"A researcher is asked to determine whether or not a productivity objective (in dollars) of better than $75,000 per employee is possible. A productivity test is done involving 20 employees. What conclusion would you reach? The sales results are as follows"

Answer 1

Based on the complete information, we can conclude that the productivity objective is not better than $75000 per employees.

From the complete information, the number of employees is  29, standard deviation is 18968.117 and the mean is 75500. Then, the t-value will be:

= (75500 - 75000) / (18967.17 / ✓20)

= 0.1179

The table value of t at 5% level of significance will be 1.7291. Therefore, the null hypothesis will be rejected.

In conclusion, the productivity objective is not better than $75000 per employee.
