Final answer:
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.
