Demand for iTunes

In the Managerial Solution, we estimated a focus group's demand function for iTunes downloads. The estimated coefficient on price is -413, and thet-statisticis -12.6.

1. Using these values, what is the standard error of this estimated coefficient?
2. Suppose we had another focus group sample, ran a regression on that sample, and obtained the same coefficient on price but with a standard error 10 times as large. What can you say about the statistical significance of the price coefficient in this second sample?
