Ok I will give you two problems, the first problem I have already done, the reason I am showing you the first problem is because the second problem piggybacks off this one, so here is the first problem which i already got the answer to (hopefully correct) :
we sample 35 students with same mean and standard deviation as above. If we were to take the average of the 35 students’ scores, what is the probability that their average would be higher than 1150?
The fact that it is asking for the average throws me off. Is this problem supposed to be set up like the first one?
- Student scores follow a Normal Distribution with the mean of 1100 and a standard deviation of 150. What percentage of individual students would you expect to get a score of 1150 or higher? now what I got was
