This is open book and open note exam but NOT to be work on with any other person (online or in person). 1) The aim of this study was to investigate the weight loss after three different diets. Please create a new variable called weightlost, which represents the difference between weight before the diet treatment and the weight after 6 weeks of diet treatment. Furthermore, the researcher thinks that a weight loss of more than 5kg is considered an effective response to the diet treatment. Please create another variable called wlostcat, which has two levels: effective if the weight loss is larger than 5kg; noeffective if the weight loss is smaller or equal than 5kg. Provide a screenshot of the data in SAS. This diet data set contains information about a study that investigated 78 people using one of three diets. There are seven variables in this dataset. The name and a brief variable description are listed below
