7. We would like to estimate the partial effect of npvis on In(bwghr). However, we want a single value to describe this relationship. One intuitively appealing measure is the average partial efiect (APE). After computing the partial eflect and plugging in the estimated parameters, we average the partial effects for each unit across the sample. Suppose that the sample average of npvis is 11.62. What is the APE of npvis on In(bwght)?
