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 \(\alpha = 0.10\), do you have enough evidence to reject the restaurant's claim? Complete parts (a) through (e).

(a) Identify the null hypothesis and alternative hypothesis.

Options:
- A: \( H_0: \mu \leq 910 \)  
  \( H_a: \mu < 910 \) (claim)  
- B: \( H_0: \mu = 910 \) (claim)  
  \( H_a: \mu \neq 910 \)  
- C: \( H_0: \mu \leq 920 \) (claim)  
  \( H_a: \mu > 920 \)  
- D: \( H_0: \mu > 920 \)  
  \( H_a: \mu \leq 920 \) (claim)  
- E: \( H_0: \mu < 910 \) (claim)  
  \( H_a: \mu \geq 910 \)  
- F: \( H_0: \mu \neq 920 \) (claim)  
  \( H_a: \mu = 920 \)  

Selected Option:
- C: \( H_0: \mu \leq 920 \) (claim)  
  \( H_a: \mu > 920 \)  

(b) Identify the critical value(s). Use technology.
