question B

Suppose that we are to conduct the following hypothesis test Ho : # = 950 H1 : p > 950 Suppose that you also know that o = 180, n = 80, a - 978.8, and take a = 0.01 Draw the sampling distribution, and use it to determine each of the following 978.8 - 950 A. The value of the standardized test statistic: 180 V 80 Note: For the next part, your answer should use interval notation. An answer of the form ( co, a) is expressed (-infly, a), an answer of the form (b, co) is expressed (b, (-oo, a) U (b, oo) is expressed (-infty, a)U(b, infty) B. The rejection region for the standardized test statistic. ( -co, 2.57 ) U( 2 57,co)
