A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is less than or equal to 922 milligrams. A random sample of 49 breakfast sandwiches has a mean sodium content of 925 milligrams. Assume the population standard deviation is 11 milligrams. At a = 0.05, do you have enough evidence to reject the restaurant's claim? t* = ヌー X-H Z = S/Vn Ho: H + 912 912 Test statistic: Decision:
