Listed below is a frequency distribution showing the advertising expenditures for 78 manufacturing companies located in the Southwest. The mean expense is $49.87 million and the standard deviation is $11.68 million. Is it reasonable to conclude the sample data are from a population that follows a normal probability distribution?
