Is there a relationship between weekly sales revenue ($000) of a coffee shop and the size of the coffee shop (square metres), the number of chairs in the coffee shop and the number of hours, per week, a competitor coffee shop is open? A random sample of coffee shops was selected, data collected on these variables and EXCEL then used to create a regression. Part of the regression output is provided here: Which of the following is the correct statement, when testing the coefficients of the independent variables, at a of 0.05? Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 15433.76 6610.97 2.33 0.03 1844.72 29022.8 Size 28.92 11.2 2.58 0.02 5.9 51.94 Chairs 172.22 119 1.45 0.16 72.38 416.82 Hours - 5.39 1.85 - 2.92 0.01 -9.19 -1.59 O None of these choices is correct. O The coefficients of Size, Chairs and Hours are significantly different to zero. O None of the coefficients are significantly different to zero. O The coefficients of Size and Hours are each significantly different to zero. O Only the coefficient of Chairs is significantly different to zero
