1. A study on weight loss in males was conducted over a five-month period. Participants came to a clinic at the beginning of each month, and their weight as well as their responses to six survey questions regarding weight loss were obtained. The raw data file WLSurveys.dat contains variables for subject ID, height (in), weight (lb) at each of five visits, and responses to questions 1-6 at each of five visits. Note that the first six survey responses are from visit one, the next six survey responses are from visit two, and so on, for a total of 30 survey responses.

B- The survey questions were measured on a scale of 0 (least) to 3 (most).

However, the data were recorded inconsistently by data entry clerks; and questions 2, 3, and 5 (for every visit) were accidentally recorded in the reverse order (0=most and 3=least). Convert questions 2, 3, and 5 for every visit so that they are measured in the same direction as the other questions.
