The answers I got for 7.67 was Test statistic: -4.3, Degrees of freedom was 29, P-value was .0002 and for the Confidence interval I got (-2.281,-.8114) Using the data from 7.67 the question is, the purchase price of a water bottle was analyzed using the two-sample t procedures that do not assume equal standard deviations. Compare the means using signifiance test and find the 95 % Confidence Interval for the difference using the pooled methods. How do the results compare with those you obtained in Exercise 7.76

7.67 Sadness and spending. The "misery is not miserly" phenomenon refers to a person's spending judgment going haywire when the person is sad. In a study, 31 young adults were given $10 and randomly assigned to either a sad or a neutral group. The participants in the sad group watched a video about the death of a boy's mentor (from The Champ), and those in the neutral group watched a video on the Great Barrier Reef. After the video, each participant was offered the chance to trade $0.50 increments of the $10 for an insulated water bottle.33 Here are the data: SADNESS
