1. The board of directors of a professional association conducted a random sample survey of 30 members to assess the effects of several possible changes in membership dues. The predictor X_{i} denotes, in dollars, the change in annual dues from the previous year posited in the survey interview to the *i*-th subject. So, for example, if X_{i} = 10, then the board is proposing a $10 increase in dues, and if X_{i} = 0, then there is no change. The response is binary with Y_{i} = 1 if the interviewee indicated that the membership would NOT be renewed at that amount of change in dues and Y_{i} = 0 if the membership would be renewed. The output for ﬁtting the logistic regression model is given below. Use this to answer the following questions.

How can I get the probability of not renewing membership? I want to estimate the probability that someone does not renew membership when annual dues increase $22.
