poppulation with a mean=100,standard deviation population=10, and n=40.

1) find mean of all values in apoplution.
2) find standard deviation population
3) p(82 LESS THAN 82 less than 97 find mean)

It seems that the data for 1 and 2 are in your description of the problem.

I don't understand 3. It would be helpful to proofread your questions before you post them.
