Hi.
I was doing practice questions from BT Notes. There are questions here that require you to compute the probability from the t stat(Miller, Chapter 7). Can anyone help me with that?
Specifically, I'm referring to End of chapter Q&A Questions 1 and 2 on page 139.
Also(please refer the image attached alongwith), in Q1, shouldn't the probability that the true mean lies above 40 be 30%, instead of 70%?
70% should be the probability from negative infinity till 0.54. So the probability of mean being greater than 40 should be 30%. Where am I going wrong here?
