## Please Help 5

1. Given H naught: with a mean greater than 85 and P-Value=0.006. What is the decision at the 0.01 level of significance?

2. Find the critical t values for a sample with n=15 and a=0.05 if H null: with a mean less than or equal too 20.

I greatly appreciate any one's help. These are problems I have struggled with this semester....and now that the end is winding down I would love to figure them out for future references. Thank so much to everyone!
