Question
A fast food restaurant estimates that the mean sodium content in one of its breakfast sandwiches is no more than 920 milligrams. A random sample of 30 breakfast
sandwiches has a mean sodium content of 910 milligrams. Assume the population standard deviation is 25 milligrams. At a = 0.10, do you have enough evidence
to reject the restaurant's claim? Complete parts (a) through (e).
(a) Identify the null hypothesis and alternative hypothesis.
Ο. H0 μ 910.
Ha: H<910 (claim)
B. Ho: µ= 910 (claim)
Ha: µ#910
C. H0: με920 (claim)
Ha: u> 920
Ο D. Ho: μ > 920
Ha: µs 920 (claim)
E. Ho: µ<910 (claim)
Ha: µ2910
O F. Ho: µ# 920 (claim)
Ha: u= 920
(b) Identify the critical value(s). Use technology.
Zo =
