For this study, we should use z-test for a population proportion > b. The null and alternative hypotheses would be: Ho: PY = 109 (please enter a decimal) H1: p v V = 09 (Please enter a decimal) c. The test statistic z v V = -0.630 (please show your answer to 3 decimal places.) d. The p-value = 0.5283 (Please show your answer to 4 decimal places. ) e. The p-value is s v X a f. Based on this, we should Select an answer ] the null hypothesis
