A fast food restaurant estimates that the mean sodium content in one if its breakfast sandwiches is no more than 922 milligrams. A random sample of 45 breakfast sandwiches has a mean sodium content of 913 milligrams. Assume the population standard deviation is 19 milligrams. At a=0.01, do you have enough evidence to reject tge restaurant's claim? i) Identify the null hypothesis and alternative hypothesis. ii) Identify the critical value(s) and the rejection region(s). iii) Identify the standardized test statistic. iv) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of tge original claim.
