16.41 Consumer perceptions of food safety.

CASE 16.2 The food safety survey data described in Case 16.2 (page 16-10) and Exercise 16.40 also contain the responses of the 303 subjects to the same question asked about food served at fast-food restaurants. These responses are the values of the variable “sfast.” Is there a systematic difference between the level of concern about food safety at outdoor fairs and at fast-food restaurants?
