Sandy likes to go to Costco to get her gas. Her husband, Terry, believes
it is not necessary to drive that far to get gas. Terry decided to test his
ideas by looking at prices from 5 stations on selected days during the
last month. Terry believes the prices at all 5 stations are similar
enough, thus it is not necessary to go to Costco for gas. The sample
of prices are listed below.
OSTCO: $3.89, $4.01, $3.97, S3.92, $4.02 76: $4.23, $4.31,
$4.19, $4.27, $4.29
CHEVRON: $4.31, $4.38, $4.42, $4.33, $4.41
ARCO: $4.17, $4.27, $4.25, $4.33, $4.28
TEXACO: $4.29, $4.33, $4.39, $4.32, $4.42
A. Terry wants to do an ANNOVA test to test his claim. Can he? Explain.
B. If the answer to part a. is yes, go ahead and test Terry's claim at
the.05 significance level.
