Mining 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
What is the 95% confidence interval for the diffe
Part B
Is this 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?
