Question

In a hypothesis test with hypotheses H0 : p = 0.26 and H1 : p ? 0.26, a random sample of size 809 produced a sample proportion of 0.2875. The test is to be made at the 10% significance level. What are the critical values of z? -1.645 and 1.645 -1.28 and 1.28 -1.314 and 1.314 -2.33 and 2.33 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?
