Question
Raquel runs a BBQ restaurant. She would like to know if the mean number of children that choose beef ribs daily is different from the average number of children that choose pork ribs daily in anticipation of creating a new children's menu. She asks her servers to make a special note every time they take an order from a child and record it in the log book. After 15 days, she records that an average of 39 children every day order beef ribs and 43 order pork ribs. The standard deviations for those 15 days are 3.1 for beef ribs and 2.9 for pork ribs, respectively. (a) Create a 95% confidence interval for the true difference in mean number of children that order beef and pork ribs recorded as (beef - pork). (b) Using the t-table, determine the test statistic and p-value for testing if there is a difference in the mean number of children that order beef and pork ribs daily. You do not need to perform a complete test.
