In order to conduct a hypothesis test for the population proportion, you sample 320 observations that result in 128 successes. He: p = 0.45; HA: P < 0.45. a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test statistic a-2. Find the p-value. p-value < 0.01 0.01 s p-value < 0.025 2 0.025 s p-value < 0.05 0.05 s p-value < 0.10 p-value > 0.10 a-3. At the 5% significance level, What is the conclusion? Reject He since the p-value is greater than significance level. Reject He since the p-value is smaller than significance level. Do not reject He since the p-value is greater than significance level. Do not reject He since the p-value is smaller than significance level. We conclude that the population mean is less than 0.45. We cannot a-4. Interpret the results at a = 0.05.
