**Transcription:**

The maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.2 parts per million (ppm). A consumer health group measured the level of the chemical in a random sample of tomatoes obtained from one producer to determine whether the mean level of the chemical in these tomatoes exceeds the recommended limit. Determine the null and alternative hypotheses.

A. 
- \( H_0: \mu = 0.2 \text{ ppm} \)
- \( H_a: \mu \neq 0.2 \text{ ppm} \)

B. 
- \( H_0: \mu = 0.2 \text{ ppm} \)
- \( H_a: \mu > 0.2 \text{ ppm} \)

C. 
- \( H_0: \mu < 0.2 \text{ ppm} \)
- \( H_a: \mu > 0.2 \text{ ppm} \)

D. 
- \( H_0: \mu > 0.2 \text{ ppm} \)
- \( H_a: \mu = 0.2 \text{ ppm} \)
