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 0.10 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? What are the null and alternative​ hypotheses? A. Ho​: Head injury measurements are not affected by an interaction between 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. B. Ho​: Head injury measurements are affected by an interaction between type 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. C. Ho​: Head injury measurements are not affected by type of car. H1​: Head injury measurements are affected by type of car. D. Ho​: Head injury measurements are not affected by size of car. H1​: Head injury measurements are affected by size of car. Find the test statistic. F = _____________ ​(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 (1)___________0.10​, (2)__________Ho. There is (3)_______evidence to support the alternative hypothesis. Conclude that there (4)________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. _____________________________________________________ 5: Data Table Size of Car Small Medium Large Foreign 291 250 340 548 501 696 507 396 333 Domestic 408 472 217 374 368 331 370 345 168 _____________________________________________________ _____________________________________________________ Source DF SS MS F P Type 1 36360 36360.1 2.42 0.146 Size 2 14396 7198.2 0.48 0.630 Interaction 2 41221 20610.7 1.37 0.290 Error 12 180113 15009.4 Total 17 272091 _____________________________________________________ Find the correct answer below: (1) less than or equal to greater than (2) reject fail to reject (3) sufficient insufficient (4) does not does
