Hi
 1) Take a random sample of those who have used it 
 2) Determine the mean and standard deviation for that sample: 
 3) complete a Hypothesis test at .05
Ho: u = 80 (claim)
Ha: u ≠ 80
 4) Use a t-test 
 5) determine the p-value
 6) IF  p-value > .05 (do not reject Ho), test would indicate u = 80
Wish You the Best in your Studies.
