A company has randomly selected a number of employees to test the effectiveness of a speed-reading course. If the course is found to significantly increase reading speed, it will be offered to all of the firm’s clerical employees. For each of the employees selected for the test, reading speeds (words per minute) before and after the course are listed in data file XR14019. Using the 0.01 level of significance in evaluating the effect of the course, should the firm offer the program to all of its clerical employees? Identify and interpret the p-value for the test.
