Clark Heter is an industrial engineer at Lyons Products. Hewould like to determine whether there are more units produced onthe night shift than on the day shift. The mean number of unitsproduced by a sample of 57 day-shift workers was 348. The meannumber of units produced by a sample of 67 night-shift workers was353. Assume the population standard deviation of the number ofunits produced on the day shift is 23 and 33 on the nightshift.Using the 0.02 significance level, is the number of units producedon the night shift larger?a. State the null and alternatehypotheses. (Click to select)
H0: μDay ≥ μNight H1: μDay < μNight
H0: μDay ≥ μNight H1: μDay > μNight
H0: μDay ≥ μNight H1: μDay = μNight b. Compute the teststatistic. (Negative values should be indicated by aminus sign. Round your answers to 2 decimal places.)
c. Computethe p-value. (Round your answer to 4decimal places.)
d. What is your decision regarding the nullhypothesis?
multiple choice 2
Reject H0
Do not reject H0
e. Using the 0.02 significance level, is thenumber of units produced on the night shift larger?
multiple choice 3
Yes
No
