9.A branch manager of McDonalds is responsible for the profitability of restaurants in Florida, Georgia, Alabama, and Tennessee. She wants to see if different types of sandwiches (hamburger, cheeseburger, filet-o-fish, and big mac) are purchased similarly across her four assigned states. She takes a random sample of McDonalds restaurants from Florida, Georgia, Alabama, and Tennessee, and calculates a chi square test statistic of 2.589 and a p-value = 0.7682.
What conclusion can she make with alpha = 0.05?
Group of answer choices
A.)With a p-value less than 0.05, we have moderate evidence that sandwiches are not purchased similarly across the four different states.
B.)With a p-value greater than 0.05, we have very strong evidence that sandwiches are not purchased similarly across the four different states.
C.)With a p-value greater than 0.05, we have no evidence that sandwiches are not purchased similarly across the four different states.
D.)We are 95% confident that the true population distribution is in the interval (0.7682, 2.589).
