I need some help with my managerial statistics problem

Problem:

= 0.05 for each data

1. Mean sales per week exceed 42.5 per salesperson( Ho u=42.5 . Ha u>42.5) u =mean

2. Proportion receiving online training is less than 55% ( Ho p=0.55 , Ha p

3 Mean calls made among those with NO training is at least 145 (Ho u =145 , Ha u>145)

4. Mean time per call is 14.7 minutes ( Ho u=14.7 , Ha is NOT= 14.7)

Use either the p-value or the critical values to draw conclusions.
