TASK 5 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
What is the 95% confidence interval for the difference of sample means?

Part B
Is the sample mean difference within the confidence interval you computed in part A of this task?

Part C
Is the difference of the sample means statistically significant?

Part D
What can you conclude about the color of the L-Bow-Roni box?

--The standard deviation of the sample mean differences in the last task was 0.69. Using this standard error, we can calculate the confidence interval at 95%, which means within two standard deviations. We can calculate other confidence intervals as well, but remember that when we test for the significance of the sample mean difference, we’re usually testing whether the difference falls within the 95% confidence interval that corresponds to a 5% significance level. In this way, we can determine whether the difference is statistically significant.--
