3. At Phil & Jims steak Shop in Parkside [best cheese steak on the planet] they sell about 750 cheese steak sandwiches per day.
They expect that the mix of sandwiches will be 360 with fried onions only, 165 pizza steask, 120 mushroom steaks & 105 with no cheese.
Last Wednesday they sold 370 with fried onions, 175 pizza steaks, 110 mushroom steaks & 95 with no cheese.
At a 95% level of confidence, did their observations fit with their expectations?
