Question

A new program may reduce the proportion of employees who fail a computer skills course. The company that developed this program supplied materials and teacher training for a large-scale test involving nearly 8500 employees in several different sites. Statistical analysis of the results showed that the percentage of employees who did not pass the course was reduced from 15.9% to 15.1%. The hypothesis that the program produced no improvement was rejected with a P-value of 0.023.
a) Explain what the P- value means in this context.
b) Even though this program has been shown to be significantly better statistically, why might you not recommend that your company adopt it?
