1. The average time that it takes an employee to make a certain
product is 45 minutes. The research department claims that a new
process can reduce this time. A sample of 25 people using the new
process yielded an average of 43 minutes. The standard deviation of
the population is known to be 7 minutes. The company statistician
devised the following hypothesis test: Ho: µ >= 45 Ha: µ < 45
Find the p value for the given test. Show work. w assume that the
population standard deviation is not known. The sample standard
deviation was found to be 6 minutes. a. Find the calculated t B.
Find the P value
