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
Computerized	Electronic
Car	Compact	51	41
Intermediate	55	44
Full-sized	62	47

Find the value of the test statistic. (Round your answer to two decimal places.)

__________

Find the p-value. (Round your answer to three decimal places.)

p-value = __________

State your conclusion:

-Reject H₀. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers.

-Reject H₀. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers.

-Do not reject H₀. There is sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers.

-Do not reject H₀. There is not sufficient evidence to conclude that the mean tune-up times are not the same for both analyzers.
