Question
A recent study stated that if a person chewed gum, the average number of sticks of
gum he or she chewed daily was 8. To test the claim, the researcher selected a
random sample of 36 gum chewers and found the mean number of sticks of gum
chewed per day was 8. The standard deviation of population is 1. at a = 0. 05, is
the number of sticks of gum a person chews per day actually greater than 8.
There is not enough evidence to support the claim that average is greater than
8.
There is enough evidence to support the claim that average is greater than 8.
There is enough evidence to support the claim that average is smaller than 8.
There is not enough evidence to support the claim that average is greater than
8.
