b-2. Find the p-value. p-value < 0.01 0.01 s p-value < 0.025 0.025 s p-value < 0.05 0.05 s p-value < 0.10 p-value z 0.10 b-3. At the 5% significance level, What is the conclusion? 2 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 differs from 0.45. We cannot conclude that the population mean differs from 0.45. We conclude that the population proportion differs from 0.45. We cannot conclude that the population proportion differs from 0.45. b-4. Interpret the results at a = 0.05.

Interpret the results at a = 0.05.
In order to conduct a hypothesis test for the population proportion, you sample 320 observations that result in 128 successes. 2 He: p= 0.45; HA: P = 0.45. b-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.)
