Using the accompanying data of restaurant sales, determine if the variance of weekday sales is the same as that of weekend sales for each of the three variables (lunch, dinner, and delivery). Click the icon to view the restaurant sales data. Is there sufficient evidence at the 0.01 level of significance to conclude that the variance of weekday sales is the same as that of weekend sales for lunch sales? Determine the null hypothesis, Ho, and the alterative hypothesis, H₁ Let weekend sales be population 1 and weekday sales be population 2. 2 2 100 0 2 2 0 Ho 0-0 H₁: 0-0 (Type integers or decimals. Do not round.) Compute the test statistic. 3.95 (Round to two decimal places as needed.) Find the one-tail p-value for the test.
