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.

Part A
Question
Determine the 95% confidence interval for the difference of the sample means. Then complete the statements.

The 95% confidence interval is
to
.

The value of the sample mean difference is 1.74, which falls
the 95% confidence interval.

Part B
Question
Which statement is true about the difference of the sample means?

The difference of the sample means is not statistically significant because it falls within the 5% significance level.
The difference of the sample means is not statistically significant because it falls outside the 5% significance level.
The difference of the sample means is statistically significant because it falls outside the 5% significance level.
The difference of the sample means is statistically significant because it falls within the 5% significance level.
