Transcribed Image Text:A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 914 miligrams. A random sample of 54 breakfast sandwiches has a mean
sodium content of 908 milligrams. Assume the population standard deviation is 20 miiligrams. At a0.01, do you have enough evidence to reject the restaurant's claim? Complete parts (a)
through (e).
(a) Identify the null hypothesis and alternative hypothesis.

(b) Identify the critical value(s). Use technology.
(Use a comma to separate answers as needed. Round to two decimal places as needed.)
identity the rejection region(s). Select the corect choice below.
OA The rejection region is z233.
B. The rejection regions are z2.33 and z< -233.
OC. The rejection region is z>2.33.
(c) identify the standardized test statistic. Use technology.
