**Exhibit 10-19**Two major automobile manufacturers have produced compact cars with the same size engines. We are interested in determining whether or not there is a significant difference in the MPG (miles per gallon) of the two brands of automobiles. A random sample of eight cars from each manufacturer is selected, and eight drivers are selected to drive each automobile for a specified distance. The following data show the results of the test.| Driver | Manufacturer A | Manufacturer B ||--------|----------------|----------------|| 1 | 32 | 28 || 2 | 27 | 22 || 3 | 26 | 27 || 4 | 26 | 24 || 5 | 25 | 24 || 6 | 29 | 25 || 7 | 31 | 28 || 8 | 25 | 27 |Refer to Exhibit 10-19. What procedure in Excel would we use to conduct a hypothesis test?- ☐ Anova: Single Factor- ☐ t-Test: Paired Two Sample for Means- ☐ z-Test: Two Sample for Means- ☐ t-Test: Two Sample Assuming Unequal Variances**Explanation of the Procedure:**This scenario involves comparing the means of two independent samples (Manufacturer A and Manufacturer B) to see if there is a significant difference between them regarding fuel efficiency.When choosing a statistical test:- If the variances of the two samples are assumed unequal, a "t-Test: Two Sample Assuming Unequal Variances" is appropriate.- If the samples are paired (e.g., the same vehicle tested under different conditions), a paired t-test would be appropriate, but this does not apply here since the samples are independent.Thus, for this analysis, you would likely select the option to conduct a "t-Test: Two Sample Assuming Unequal Variances" to account for any potential differences in sample variance.
