# Construct hypothesis tests in Excel for employee's

Use alpha = 0.05 unless specified otherwise. For each hypothesis test state HA (the research hypothesis) and H0 (the null hypothesis) using the proper symbols. (You can type mu or sigma for the corresponding symbols.) Include a "summary statement" for each hypothesis test.

A formal Summary Statement is REQUIRED as part of all solutions that include a CI or hypothesis test.

FACTS:

The managing partner of a major consulting firm is trying to assess the effectiveness of expensive computer skills training given to all new entry-level professionals. In an effort to make such an assessment, she administers a computer skills test immediately before and after the training program to each of the 40 randomly chosen employees. The pre-training and post-training scores of the 40 individuals are recorded in the data file below.

Use excel format and functions to solve the following:

(a) Using a 10% level of significance, do the given sample data support the claim that the organization's training program is increasing the new employee's working knowledge of computing?

(b) Using a 1% level of significance, do the given sample data support the claim that the organization's training program is increasing the new employee's working knowledge of computing?
