Question

Question 8 3 pts The p-value for a Hypothesis Test of a mean or proportion O All the answers are correct Is based on the probability of the test statistic on out in the relevant tail(s) of the distribution Is twice as large if it is a two-tailed test O is compared with alpha to make a conclusion in a hypothesis test

Answer 1

8) all the above are correct

11)

z value for uper tail test at 0.1 level =1.28 (it does not depend on sample size)

12)

for 0.01 level critical value z =2.576

13)

test statistic =(Xbar-mean)*sqrt(n)/standrd deviation =(3.761-3.4)*sqrt(17)/0.729 =2.0418
