Question: (7 pts) The data for this problem are on the sheet "Fast Food Sales."

The general manager of a chain of fast food chicken restaurants wants to determine how effective their promotional campaigns are. In these campaigns "20% off" coupons are distributed. These coupons are only valid for one week. To examine their effectiveness, the executive records the daily gross sales (in $1,000s) in one restaurant during the campaign and during the week after the campaign ends.

Test the null hypothesis that the campaign has no effect on sales vs the alternative that the campaign increases sales at the 10% significance level. Report a p-value and state your conclusion.
