On a productivity scale from 1 to 15, the average productivity score for all companies in the US is 8 (u = 8.00, 0 = 4.00). The 10 psychologist randomly samples 5 companies and has the companies implement a 2-hour lunch break for 1 month. At the end of the month, the 10 psychologist measures the productivity scores for the five companies and obtains the following scores: 9, 14, 10, 12, 15 Using the appropriate hypothesis test and the six steps of hypothesis testing, determine what the 10 psychologist should conclude about the effect of a 2-hour lunch break on employee productivity. 1)calculate the exact p-value 2) Based on the results of your analysis, does a 2-hour lunch break increase, decrease, or have no effect on productivity.
