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: alcohol_i = per capital alcohol consumption (in gallons) in location i and hours_i= the number of hours that liquor stores were open in location i. You estimate the regression model by OLS: alcohol_i=beta_0+beta_1*hours_i+u_i and obtain the following results alcohol_i=2.76+0.528*hours_i: with the standard error being 0.015 and 0.127, n=600, R-squared=0.07. Test the null hypothesis that the variable hours is a statistically significant predictor of alcohol. What is you conclusion?
