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?
we’re studying how colors may affect a consumer when buying a pasta box
my teacher told me i shouldn’t focus on the “1.74” value because then it would always lie within the interval making it always statistically significant, they told me to focus on what the mean difference would be if the colors didn’t matter, i answered 0, would that be correct?
