  • The mean gas mileage for a hybrid car is 56 miles
    per gallon. Suppose that the gasoline mileage is
    approximately normally distributed with a
    standard deviation of 3.2 miles per gallon.
  • . A random sample of size 15 is selected from a
    normal population. The population standard
    deviation is unknown. Assume the null hypothesis
    indicates a two-tailed test and the researcher
    decided to use the 0.10 significance level. For
    what values of t will the null hypothesis not be
    rejected?
