A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 921 milligrams. A random sample of 36 breakfast sandwiches has a mean sodium content of 909 milligrams. Assume the population standard deviation is 25 milligrams. At α=0.10​, do you have enough evidence to reject the restaurant's claim?    -Identify Ho and Ha. -Find the critical value and sketch the region -Calculate the test statistic -Do you reject Ho or fail to reject Ha
