*An experimenter is interested in the hypothesis testing problem with Ho: μ = 420 versus H₂: μ< 420, where u is the average radiation level in a research laboratory. Suppose that a sample of 49 radiation level measurements is obtained and that the experimenter wishes to use o=10.0 for the standard deviation of the radiation levels. (a) What is the rejection region when a-0.01? (b) Suppose that the sample mean is 415.7. What would be the experimenter's decision of the hypothesis test based on the rejection region? (c) What is the p-value for this hypothesis test?

Question

please solve the attached question manually and via R-studio.

An experimenter is interested in the hypothesis testing problem with \( H_0: \mu = 420 \) versus \( H_a: \mu < 420 \), where \( \mu \) is the average radiation level in a research laboratory. Suppose that a sample of 49 radiation level measurements is obtained and that the experimenter wishes to use \( \sigma = 10.0 \) for the standard deviation of the radiation levels. (a) What is the rejection region when \( \alpha = 0.01 \)? (b) Suppose that the sample mean is 415.7. What would be the experimenter’s decision of the hypothesis test based on the rejection region? (c) What is the p-value for this hypothesis test?
