In the Managerial Solution, we estimated a focus group's demand curve for iTunes downloads. The estimated coefficient on price was
negative 413−413,
and the t-statistic was
negative 12.8−12.8.
Using these values, what is the standard error of this estimated coefficient?
The standard error of the price coefficient is
32.2732.27.
(Enter your response rounded to two decimal places.)
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
fivefive
times as large. What can you say about the statistical significance of the price coefficient in this second sample?
The price coefficient
