The stаte оf Minnesоtа wаnts tо know whether restricting the opening hours of liquor stores reduces alcohol consumption. You gather a data set that contains the following information: a l c o h o l i = per capital alcohol consumption (in gallons) in location i and h o u r s i = the number of hours that liquor stores were open in location i. You estimate the regression model by OLS a l c o h o l i = β 0 + β 1 h o u r s i + ε i and obtain the following results (standard errors are given in parenthesis) a l c o h o l ^ = 2 . 76 + 0 . 528 h o u r s i . n=600, Rsquared =0.07 Test the null hypothesis that the variable hours is a statistically significant predictor of alcohol. What is you conclusion?
