Question

an insurance company is attempting to see if two different chains of autobody repair shops give different estimates of repair costs. they take seven random cars to one chain, another seven random cars to a second chain, and obtain estimates. these estimates, in hundreds of dollars, are in the following table. chain 1 2 3 4 5 5 5 4 chain 2 1 4 5 7 6 7 1 a. which of the following tests available in the data analysis tool in excel should be used to carry out the analysis? t-test: two sample assuming unequal variances anova: single factor t-test: paired two sample for means z-test: two sample for means t-test: two sample assuming equal variances

Answer 1

The appropriate test to carry out the analysis in this case would be the one-way ANOVA test. By conducting a one-way ANOVA test, we can determine if there is a significant difference in the repair cost estimates between the two chains of repair shops.

Step-by-step explanation:

The appropriate test to carry out the analysis in this case would be the one-way ANOVA test.

The one-way ANOVA test is used when we want to compare the means of multiple groups. In this case, the two chains of autobody repair shops represent the different groups.

By conducting a one-way ANOVA test, we can determine if there is a significant difference in the repair cost estimates between the two chains of repair shops.
