A political analyst believes that a senator's recent decision to support a bill resulted in a drop of approval ratings. To test thisclaim, he selects random cities in the state that voted the senator in and compares the approval ratings before the decisionto the approval ratings after the decision. Suppose that data were collected for a random sample of 8 cities, where eachdifference is calculated by subtracting the percent approval rating before the decision from the percent approval rating afterthe decision. Assume that the percentages are normally distributed. What type of test is this hypothesis test?Select the correct answer below:This is a left-tailed test because the alternative hypothesis is H. : Ha < 0.This is a left-tailed test because the alternative hypothesis is H, : Ha > 0.This is a two-tailed test because the alternative hypothesis is H, : µa # 0.This is a right-tailed test because the alternative hypothesis is H, : Ha > 0.This is a right-tailed test because the alternative hypothesis is H, : µa < 0.

Four scenarios of statistical studies are given below. Decide which study uses a population parameter. Answer O Lakeside Family Dentistry reported that 6 of the 15 patients who came in for a regular cleaning one day had at least one cavity. O As part of her senior project, Kaisa asked 84 of her classmates if they voted in the last presidential election. 39 said yes. O of 351 dog owners who were surveyed, 70 reported owning two dogs. The average finish time for the Ironman, Kona was 11:32 for the 1883 finishers, with an average swim time of 1:14, an average bike time time of 4:14.
A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?
In a fishing lodge brochure, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 65 out of a random sample of 78 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the population proportion of guests who catch pike over 20 pounds is different from 75% (either higher or lower)? Use ? = 0.05. -What is the value of the sample test statistic? (Round your answer to two decimal places.) -What is the value of the sample test statistic? (Round your answer to two decimal places.)
One of the more popular statistics reported in the media is the president's job approval rating. 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 of registered voters. Complete parts (a) and (b) below. (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.) a) This proportion tends to fluctuate from week to week. Name some reasons for the fluctuation in the statistic. Select all valid reasons below. A. The proportion could be changing due to a large change in the composition of the population. B. The proportion could be changing due to sampling error; different people are in the sample. C. The proportion could be changing because the sampling size of the poll is changing. D. The proportion could be changing because people's attitudes are changing

40 people are randomly sent to walk one of four trails. The time (in minutes) they spend completing each trail is recorded in the table below. (a) Test to see if the times needed to complete a trail vary. Use a 0.05 significance level. (b) Test each pair (A/B, A/C, A/D, B/C, B/D, C/D) to see which trails have a statistically significant difference. Indicate your p-value for each comparison, and when the effect is statistically significant (use 0.05 as your significance level), declare which trail of the two takes more time to complete. Trail A - 30, 33, 41, 27, 36, 31, 37, 40, 29, 35 Trail B - 27, 33, 38, 41, 40, 38, 35, 44, 41, 39 Trail C - 25, 34, 41, 39, 32, 30, 36, 35, 27, 33 Trail D - 41, 39, 46, 37, 40, 42, 50, 42, 50, 33, 47, 43
