Question

The researcher decides to conduct a hypothesis test. They take a random sample of 15 such schools in Michigan and find a sample average of 10439 with a standard deviation of 1735. Conduct a hypothesis test to determine if the average cost of attendance at 2-year colleges in Michigan is lower than the national average. Round all numeric results to 4 decimal places. 2. Which set of hypotheses should the researcher use? A. H0: ? = 12,260 vs. HA: ? > 12,260 B. H0: ? = 12,260 vs. HA: ? < 12,260 C. H0: ? = 12,260 vs. HA: ? ? 12,260 3. Calculate the test statistic. -4.0650 4. Calculate the p-value. .0010 5. Based on the p-value, we have: A. very strong evidence B. some evidence C. extremely strong evidence D. little evidence E. strong evidence that the null model is not a good fit for our observed data. 6. Calculate a 95% confidence interval for the mean cost of attendance at 2-year colleges in Michigan. ($ 10427.8006 , $ 10450.1994 )
