1. Conduct a hypothesis test showing all of your steps. A random sample of 43 luxury car drivers showed the average distance driven between oil changes is 3187 miles with a standard deviation of 65.4 miles. A random group of 56 drivers of compact cars had the average distance driven between oil changes at 3235 miles, with a sample standard deviation of 49.1 miles. Can you claim the mean distance between oil changes is the same for all luxury car drivers and compact car drivers? Test this claim with a 5% level of significance. - State the hypotheses and label the claim. Is the test left-tailed, right-tailed, or two-tailed? -What is/are the critical value(s)? Draw a picture. -What is the P-value AND test-statistic? -State the conclusion. Give two reasons for your decision to reject/not reject H0 based on: 1) Test statistic compared to critical value 2) P-value compared to α Then, relate back to the original claim.
