Please complete the following Excel document. For the first tab (chapters 7 & 8), please fill out the boxes to find confidence intervals and then hypothesis test several different alternative hypotheses.
For part 2 (chapter 10), please find the correlation coefficient and various critical values and p-val to confirm there is correlation. Plot a scatter plot of the data too. Finally, answer the following question on your D2L submission:
What is the third lurking variable that is responsible for the correlation and why? (Note: the two variables do NOT directly affect each other (chocolate does not make you win Nobel prizes); there is a third variable that relates the two together)
