Data was collected on how much 8 customers recently spent for lunch at Benny's Café; see the Excel descriptive statistics file below. 

  1. After Joey viewed this data, he said "Wow, look how skewed this data is, what with the mean amount spent of $7.38 being so much larger than the standard deviation of $1.57." Clearly state why you do or why you don'tagree with Joey's statement.
  2. Joey continues... "This data set is really crazy, why look at all of those data outliers with the negative signs." Clearly state why you do or why you don't agree with Joey's statement.

If anyone can help with this I would be very grateful! Thank you in advance
