Question

An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow Analyzer Compact Intermediate Full-sized Computerized 49 54 65 Electronic 43 45 Car Use = .05 to test for any significant differences Source of Variation (to whole number) of Freedom (to 1 decimal) (to 2 decimals) (to 4 decimals) Treatments Blocks Error Total The p-value is 1-Select your answer- What is your conclusion? -Select your answer- | that the mean tune-up times are not the same for both analyzers Sum of Squares Degrees Mean Square p-value

Explanation / Answer

(b) The p-value is 0.12.

(c) As p-value is grater than 0.05 so we reject the null hypothesis that tune-up times are same for both analyzers. So here it is true that the mean tune-up times are not the same for both analyzers.
