1. aAn experimenter is interested in the hypothesis testing problem with H0; p. = 4-20 versus Ha: u

1. a An experimenter is interested in the hypothesis testing problem with 1-10. g = 420 versus I-Ia. g < 420, where 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 0=10.0 for the standard deviation of the radiation levels. (a) What is the rejection region when 0=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?
