A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 929 milligrams. A random sample of 35 breakfast sandwiches has a mean sodium content of 924 milligrams. Assume the population standard deviation is 20 milligrams. At α=0.05​, do you have enough evidence to reject the​ restaurant's claim? Complete parts​ (a) through​ (e). ​ (a) Identify the critical​ value(s). Use technology.
