In a hypothesis test with hypotheses H0: p ≥ 0.31 and H1: p < 0.31, a random sample of size 575

Step 1: The critical value of z is -2.33.

Question

In a hypothesis test with hypotheses $H_0: p \geq 0.31$ and $H_1: p < 0.31$, a random sample of size 575 produced a sample proportion of 0.2830. The test is to be made at the 1% significance level. What is the critical value of z? $\circ$ -2.33 $\circ$ -1.714 $\circ$ -2.58 $\circ$ -1.96 What is the value of the test statistic, z, rounded to three decimal places? i What is the p-value for this hypothesis test, rounded to four decimal places? i Should you reject or fail to reject the null hypothesis in this test?
