PROBLEM 3E

Let X have an exponential distribution with a mean of θ; that is, the pdf of X is f (x; θ) = (1/θ)e−x/θ , 0 < x < ∞. Let X1,X2, . . . ,Xn be a random sample from this distribution.

(a) Show that a best critical region for testing H0: θ = 3 against H1: θ = 5 can be based on the statistic

(c) If n = 12, find a best critical region of size α = 0.10 for testing H0: θ = 3 against H1: θ = 7.

(d) If H1: θ > 3, is the common region found in parts (b) and (c) a uniformly most powerful critical region of size α = 0.10?

The answer to “Let X have an exponential distribution with a mean of ?; that is, the pdf of X is f (x; ?) = (1/?)e?x/? , 0 < x < ?. Let X1,X2, . . . ,Xn be a random sample from this distribution.(a) Show that a best critical region for testing H0: ? = 3 against H1: ? = 5 can be based on the statistic (c) If n = 12, find a best critical region of size ? = 0.10 for testing H0: ? = 3 against H1: ? = 7.(d) If H1: ? > 3, is the common region found in parts (b) and (c) a uniformly most powerful critical region of size ? = 0.10?” is broken down into a number of easy to follow steps, and 117 words.
