Dairy Castle wanted to boost the sales of their "Country Baskets." They thought that it might be helpful to hang posters that picture the item. They recorded the number of Country Baskets sold during lunchtime for one week at their various stores. They repeated the sampling for another week when the poster advertising was used. Assume that the weekly sales are normally distributed. Is there sufficient evidence to say that hanging the posters improved the sales of the Country Baskets? Use a .05 significance level.
