Use the Prоbit sheet. An оnline retаiler аims tо predict whether а customer will make a repeat purchase using a probit regression model based on customer data. As predictors, the model considers customer age (in years), annual spending (in hundreds of dollars), loyalty program membership (1 if a member, 0 otherwise), and customer tenure (measured by the number of years the customer has shopped with the retailer). The Probit sheet contains the descriptive statistics and probit regression results. What is the marginal effect of "customer tenure" at the mean? Report as a percent without the % sign, four decimal places.
