Question: Let Y = the number of glasses broken in a particular restaurant in a week. Let X = the average age of the waiters and waitresses working the week. The regression equation is Y = 20 - .5X. Interpret the -.5 in English(in terms of the relationship between broken glasses and age). If SE( 1 )=.1 and n = 20, is X a relevant predictor of Y when =.05? [Why is the t-statistic = -5]
