Suppose you regress Ice Cream Sales on the number of children under age 10 and on binary dummy variables indicating the 2^nd,3^rd,and 4^th quarters of the year and you get (p-values in parentheses)

$\begin{array} { lllll } Ice ~\widehat {Cream}~ Sales { } _ { t } =& 17.92 +& 8.63 Under 10 _ { t } + &14.61 Q 2 _ { t } + &5.32 Q _ { t } +& 1.08 Q 4 _ { t }\\&( 0.012 ) & ( 0.032 ) &( 0.037 ) & ( 0.124 ) &( 0.179 ) \\\end{array}$
You should conclude that,holding all other independent variables constant,ice cream sales are statistically greater in

Quizplus · Accepted Answer

The coefficient on Q2 is positive and statistically significant at the 5% level (p-value = 0.037), indicating that, holding all else constant, ice cream sales are statistically greater in Q2 than in Q1. No other quarter shows statistically significant differences in ice cream sales relative to the baseline quarter (Q1).
