A company has two machines that produce components. The quality control manager is concerned that the average length of the components these machines produce is different. He calculates the 95% confidence interval for difference in true average length to be: (-1.2, 0.90). Based on this interval, would it be reasonable to say that the average lengths are the same or are different A. It would be reasonable to say they are the same since 0 is not a reasonable estimate for μ1-μ2. B. It would be reasonable to say they are the different since 0 is not a reasonable estimate for μ1-μ2. C. It would be reasonable to say they are the same since 0 is a reasonable estimate for μ1-μ2. D. t would be reasonable to say they are the different since 0 is a reasonable estimate for μ1-μ2.

A. It would be reasonable to say they are the same since 0 is not a reasonable estimate for μ1-μ2.
B. It would be reasonable to say they are the different since 0 is not a reasonable estimate for μ1-μ2.
C. It would be reasonable to say they are the same since 0 is a reasonable estimate for μ1-μ2.
D. t would be reasonable to say they are the different since 0 is a reasonable estimate for μ1-μ2.
