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 youâll determine whether the difference is significant. for the purpose of constructing the confidence interval, assume that thereâs 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 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?
