Question
In a hypothesis test with hypotheses Ho : p= 0.26 and H1 :p+ 0.26, a random sample of size 771 produced a
sample proportion of 0.2450. The test is to be made at the 1% significance level.
What are the critical values of z?
-2.12 and 2.12
-2.33 and 2.33
-2.58 and 2.58
-2.17 and 2.17
What is the value of the test statistic, z, rounded to three decimal places?
What is the p-value for this hypothesis test, rounded to four decimal places?
Should you reject or fail to reject the null hypothesis in this test?
