A fаst fооd cоmpаny clаims that the mean calorie count in their burger is at least 354. You want to test this claim. You find a random sample of 24 burgers has a mean calorie count of 340. Assume the population is normally distributed and the population standard deviation is 24.6 calories. At α = 0.05, is there enough evidence to reject the claim?
