...ber of units produced in the afternoon shift is significantly higher than the other shift.
Reject the null hypothesis if the calculated value of t is less than the critical value of t .
n Mean SD
Shift 1 54 345 21
After noon Shift 60 351 28
Calculated value of t =-1.2829
Significance level = 0.05
Degrees Freedom =112
Critical value =-1.658571
P value =0.1011
Conclusion: Accept the null hypothesis. The sample does not give enough evidence to support the claim that the mean number of units produced in the afternoon shift is significantly higher than the other shift.
