Question

Do employees perform better at work with music playing? The music was turned on during the working hours of a business with 45 employees. Their productivity level averaged 5.2. On a different day the music was turned off and there were 40 workers. The workers' productivity level averaged 4.8. What can we conclude at the .01 level, if computed p-value is 0.12?

Answer 1

We reject null hypothesis, when p value is less than significance level and fail to reject the null hypothesis, when p value is more than significance level

Significance level is 0.01 and the calculated p value is 0.12

It is clear that the p value is more than 0.01 significance level, so result is insignificant and we failed to reject the null hypothesis.

So, we can say that there is insufficient evidence to conclude that employees perform better at work with music playing.
