A veterinarian believed this result to be too high, so she randomly selected 240 pet owners and discovered that 90 of them spoke to their pet on the telephone. Does the Question list K veterinarian have a right to be skeptical? Use the a = 0.1 level of significance.

The approval rating is reported as the proportion of the population who approve of the job that the sitting president is doing and is typically based on a random sample Question list of registered voters where the sample size is the same week to week. Complete parts (a) and (b) below. Question 1 a) This proportion tends to fluctuate from week to week. Name some reasons for the fluctuation in the statistic. Select all valid reasons below. YA. The proportion could be changing because people's attitudes are changing. x Question 2 B. The proportion could be changing due to a large change in the composition of the population. Y C. The proportion could be changing due to sampling error; different people are in the sample. O Question 3 D. The proportion could be changing because the sampling size of the poll is changing. b) A poll showed the approval rating to be 0.49 (49%). A second poll based on 2000 randomly selected voters showed that 1002 approved of the job the president was doing. Do the results of the second poll indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original level? Explain. Assume the a = 0.05 level of significance. Question 4 Identify the null and alternative hypotheses for this test. O A. Ho: P = 0.49 &C. Ho: P= 0.49 O Question 5 O B. Ho: P 0.49 OD. Ho: P > 0.49 O E.
