Need help with part d. Will give thumbs up! thank you

Hourly wages at Manufacturing Plant A very from worker to worker, with an average hourly wage of $13.97, and a standard deviation of $2.3 per hour, or o plant A = 2.3. In an attempt to attract new employees, a newly constructed Manufacturing Plant B claims that its employees will be paid, on average, more than than employees at Manufacturing Plant A. Assume that the standard deviation in hourly wages at Plant B is the same as at Plant A, or o pPlant B 2.3. (a) Choose the correct statistical hypotheses. А. Но : Иplant B — 13.97 На : Иplant B > 13.97 О в. Но : ХА > 13.97 На: Хр Plant B < 13.97 Plant B A С. Но : Ирlantв 2 13.97 НА: Иplant B < 13.97 O D. Но : Хр = 13.97 На : ХРlant B > 13.97 Plant B Е.

If the mean/average hourly wage of these 44 employees is greater than $14.8, then there is enough statistical evidence to indicate that the mean hourly wage of employees at Plant B is greater than the mean hourly wage of employees at Plant A. What level of a was used here? Enter your answer to at least three decimal places. 2.3937 (c) The average of the sample of n = 44 workers was found to be X 14.51. What decision can you make from this sample? A. Employees at Plant B do not earn more on average compared to employees at Plant A. B. The sample size is too small to conduct a statistical test, so a decision cannot be made C. Employees at Plant B do earn more on average compared to employees at Plant A D. The hourly wages at Plant B need to be Normally distributed to do the test (d) If the average hourly wage of all workers at Plant B is $14.57, what is the probability of concluding using the decision criteria outlined in part (b) that the mean hourly wage of all employees at Plant B is not greater than the mean hourly wage of all employees at Plant A? Enter your answer to at least three decimals. Answer =
