Question

In order to conduct a hypothesis test for the popufation proportion, you sample 320 observations that result in 128 successes Use the p-value approach to conduct the following tests at 0° 0 05 Use Table 1 Ho, p2045; H, p<045 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Test statistic a-2. The p-value is: (Round p value to 4 decimal places.) O p-value < 0.01 O0.01 s p-value <0.025 0.025 s p-value <0.05 0.05 s p-value < 0.10 O p-value 2 0.10 a-3. What is the conclusion? O Reject Ho since the p-value is greater than a O Reject Ho since the p-value is smaller than a O Do not reject Ho since the P-value is greater than α O Do not reject Ho since the p-value is smaller than a Hyp:045. HA ρ#045 b-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places) Test statistic b.2. The p-value is (Round p-value to 4 decimal places.J) Op-value <001 001 s p-value < 0025 0.025 s p-value <0.05 0.05 s p-value <0.10 p-value 2 0.10 b-3. What is the conclusion?
