Question

Use the technology display, which results from the head injury measurements from car crash dummies listed below. The measurements are in hic (head injury criterion) units, and they are from the same cars used for the table below. Use a 0.01 significance level to test the given claim Test the null hypothesis that head injury measurements are not affected by an interaction between the type of car (foreign, domestic) and size of the car (small, medium, large). What do you conclude? EEB Click the icon to view the data table and technology display. What are the null and alternative hypotheses? A. HO: Head injury measurements are affected by an interaction between type O B. : Head injury measurements are not affected by an interaction between of car and size of the car H1: Head injury measurements are not affected by an interaction between type of car and size of the car type of car and size of the car H1: Head injury measurements are affected by an interaction between type of car and size of the car Ho. Head injury measurements are not affected by size of car H1: Head injury measurements are affected by size of car OC. H: Head injury measurements are not affected by type of car H1: Head injury measurements are affected by type of car Find the test statistic. Round to two decimal places as needed.) Determine the P-value P-value (Round to three decimal places as needed.) Determine whether there is sufficient evidence to support the given alternative hypothesis Since the P-value is 0.01, Hn. There is V evidence to support the alternative hypothesis. Conclude that there appear to be an effect from an interaction between the type of car (foreign or domestic) and whether the car is small, medium, or large

Explanation / Answer

1.B)

The test statistic F = 1.51

P-value = 0.261

Since P-value = 0.261 is greater than 0.01, there is not enough evidence to support the alternative hypothesis.

We can conclude that there do appear to be an effect from an interaction between the type of car and whether the car is small, medium or large.
