A food service manager would like to know if average sales at their cafe have increased after a new advertising campaign. They have a random sample of 7 days prior to the campaign which yielded an average sales of $1179.3/day with a standard deviation of $127.1. After the campaign they randomly sampled 12 days and found an average of $1298.2/day and a standard deviation of $186.4. What is the pvalue associated with this test?\
