Determining Whether a Difference Is Statistically significant You calculated the standard deviation of the sample mean differences to be 0.69. You also calculated the sample mean
difference to be 1.74. Now you'll determine whether the difference is significant. For the purpose of constructing the
confidence interval, assume that there's no difference between the population means.

? Question
Determine the 95% confidence interval for the difference of the sample means. Then complete the statements.
The 9596 confidence interval is
to
The value of the sample mean difference is 1.74, which falls
the 95% confidence interval.
