# This question is based on the inventory assignment from this module. In our regression, we create variables for each month except for December, allowing us to interpret the coefficients as the expected difference between a given month’s sales and December sales. Based on the regression results, which of the following months’ sales are expected to be significantly different from December? (check all that apply)

Correct! The coefficients for both January and February have p-values that are less than 0.05. The p-values for the October and November coefficients are larger, indicating that there is insufficient evidence to conclude that sales in these months is expected to differ from December.
