Ho: u (Choose one) $ (Choose one) V X 5 H1 : u (Choose one) |$ (Choose one) V This hypothesis test is a (Choose one) v test. Part: 1 / 5 Part 2 of 5 (b) Find the critical value(s). Round the answer(s) to at least three decimal places. If there is more than one critical value, separate them with commas. Critical value(s):(:2) Compute the test value. Always round I score values to at least three decimal plams. r=m (:1) Make the decision. mu... (e) Summarize the results.
