The profit per new car sold by a Winnipeg automobile dealer varies from car to car. The average profit per sale tabulated for the past 6 days was $368 with a standard deviation of $190 To test if there is sufficient evidence to indicate that average profit per sale is less than $480, the appropriate null and alternative hypotheses for the test are:

a)  H0: μ ≥ $368 vs. H1: μ < $480                                                                                  

b)  H0: μ ≥ $480 vs.  H1: μ < $480

c)  H0: μ ≤ $480 vs. H1: μ > $480

d)  H0: μ = $480 vs. H1: μ ≠ $480

t is necessary for an automobile producer to estimate the number of miles per gallon achieved by its cars. Suppose that the sample mean for a random sample of 150 cars is 30.2 miles and assume the standard deviation is 3.6 miles. Now suppose the car producer wants to test the hypothesis that μ, the mean number of miles per gallon, is 30.5 against the alternative hypothesis that it is not 30.5. Conduct a test using α=.05 by giving the...
