a, a random sample of 12 Imprezas were driven yielding the following miler per gallon
25.1 24.6 22.5 27.8 26.1 21.0 23.9 28.4 24.4 23.5 26.2 20.7
Create a 95% confidence interval estimate for the population mean mpg’s for the Subaru
b. Suppose Subaru advertises that their Imprezas have a population mean mpg of at least 22 mpg. Does the 95% confidence interval created in part a support this claim? Why or why not.
