14. A researcher claimed that for people that chew gum, the average number of sticks of gum chewed daily was greater than 8. To test the claim, she selected a random sample of 36 gum chewers and found the mean number of sticks of gum chewed per day was 9. The standard deviation of the population is 1. At a = 0.05, conduct all steps of a hypothesis test to test the researcher's claim.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
