Johnson's management team wants to try to understand the relationship between repair time and the other variables using linear regression. They want to compare mechanical failures to the base case of electrical failures and they want to compare repair times of individual repair persons to that of (the base case of) Bob Jones. Remember that the base case for each factor does not have a variable associated with it. Also remember that dummy variables only take on the values of 0 or 1. Required:
Create the dummy variables for type of repair and for repair persons.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
