Question

1 of the questions remains unanswered. Suppose that you are to conduct the following hypothesis test: H_0: mu = 480 H_1 mu notequalto 480 Assume that you know that sigma = 125, n = 46. X = 460, and take a = 0.01. Draw the sampling distribution, and use it to determine each of the following: A The value of the standardized test statistic: -1.08517 The rejection region for the standardized test statistic (-infty, -2.58)U(2.58, infty) The p-value is Your decision for the hypothesis test Do Not Reject H_1 Reject H_1 Reject H_0 Do Not Reject H_0

Explanation / Answer

A) std error=std deviation/(n)1/2=18.43

test stat z=(x-mean)/std error =-1.08517

B) rejection region (-infty ,-2.58)U(2.58, infty)

C)p value= 0.2778

d)do not reject Ho
