Question 937139: A factory works a two shift system with 50 workers on each shift. The morning shift
takes a mean time of 112 minutes with a standard deviation of 12 minutes to carry out
an assembly operation. The afternoon shift takes a mean time of 117 minutes with a
standard deviation of 9 minutes for the same operation. Test the hypothesis that the
mean time for the assembly operation is the same for both shifts at a level of
significance of 0.05 Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! Ho: p2 - p1 = 0 (claim)
Ha: p2 - pa > 0
test statistic: z(5)= = 7.7152
p(z > 7.7152) is basically 0
.....
0 < .05, reject claim that the mean time for the assembly operation is the same for both shifts
