a. (6 pts) Use your calculator to obtain a NEW simple random sample of n=5 students and record the data here.

For this project, the range is 1 - 40 and we want 5 values. For the older TIs it prints randInt( then you type 1, 40, 5). It will print 5 values. Then count through the given exam scores to get your value EX.(12 -- count to the 12th score)

YOUR EXAM VALUES: __32,39,9,15,1__________

i. Determine the sample mean: 19.2

ii. Determine the sample standard deviation: 15.881

iii. Determine the sample range: 38

iv. Does the sample mean equal the population mean?

v. Does the sample standard deviation equal the population standard deviation? NO MY SAMPLE SD IS 15.881 AND MY POPULATION SD IS 14.204

vi. Does the sample range equal the population range?

I NEED HELP IN IV AND VI. I DONT KNOW HOW TO FIND THE POPULATION MEAN AND POPULATION RANGE?? I DIDN UNDERSTAND WHERE SHE SAID COUNT TROUGH THE GIVEN EXAMN SCORES TO GET YOUR VALUE?
