Hi everyone!
I have a question about the answer of question 19a and e. question a: Find the probability that X is greater than 60. Why do they do 0,5 0,3944 and not 1  ...?
Question e was: the probability is 0,05 that X is in the symmetric interval about the mean between which two numbers? additional info: mean is 50 and sigma squared is 64. I don't really understand what I have to do here. Can anyone help me out?
Thanks in advance!
