Suppose we have collected times, in minutes, that it takes volunteers to complete a set of pencil and paper mazes. Volunteers are randomly assigned to one of two groups. Group 1 watch a 5 minute video explaining good strategies for completing the mazes. Group 2 watch a 5 minute video of other people successfully completing the mazes, but with no explanation given.Researchers are interested in testing against the null hypothesis that there is no difference in population mean times that it takes people to complete mazes after watching either type of video.There are the summary statistics after collecting data. Note that the sample sizes differ, because some subjects did not follow instructions correctly and so they were not included in the analysis.x1 = 11.98, x2 = 9.15s1 = 8.69, s2 = 7.75n1 = 43, n2 = 52a. Is this an experimental or observational study?ObservationalExperimental b. What are the predictor and response variables, and are they categorical or quantitative? (You must get all correct)Video type is categoricalFinishing time is quantitativeVideo type is the response variableVideo type is the predictor variableVideo type is quantitativeFinishing time is categoricalFinishing time is the predictor variableFinishing time is the response variableHow should the null hypothesis be written?H0: x1 - x2 = 0H0: 1 - 2 = 5 H0: = 0H0: x = 5H0: x1 - x2 = 5H0: 1 - 2 = 0(for the following calculations, round to 2 decimal places)c. Calculate the standard error of x1 - x2:d. Calculate the approximate 95% CI for 1 - 2: toe. The result of the hypothesis test is:We do not have evidence that there is a difference in population means, because the null value is inside the 95% CI.We do not have evidence that there is a difference in population means, because the null value is outside the 95% CI. We have evidence that there is a difference in population means, because the null value is inside the 95% CI.We have evidence that there is a difference in population means, because the null value is outside the 95% CI.f. What kind of error is it *possible* that we have made?1. It is possible that we made a Type I error, because this is when you reject a false null hypothesis.2. It is possible that we made a Type I error, because this is when you fail to reject a false null hypothesis. 3. It is possible that we made a Type I error, because this is when you reject a true null hypothesis.4. It is possible that we made a Type I error, because this is when you fail to reject a true null hypothesis.5. It is possible that we made a Type II error, because this is when you reject a false null hypothesis.6. It is possible that we made a Type II error, because this is when you fail to reject a false null hypothesis.7. It is possible that we made a Type II error, because this is when you reject a true null hypothesis.8. It is possible that we made a Type II error, because this is when you fail to reject a true null hypothesis. The ratio of boys to girls at Jackie Chan high school is 5:3.

False A preferred stock will pay a dividend of $1.25 in the upcoming year and every year thereafter; i.e., dividends are not expected to grow. You require a return of 12% on this stock.

A graph labeled Heating Curve has time as the horizontal axis and Temperature as the vertical axis. A line starts at 0 and rises to 1500 degrees where it levels off briefly; this section of line is labeled solid. The line continues to rise until it levels off at about 2750; this curve is labeled Liquid. After running horizontal for some time, the line rises again; this curve is labeled Gas. Based on the information in the graph, which statement best applies to a gas? Its particles have the highest average kinetic energy. Its particles have the smallest volume of all three states of matter. Its particles are slowing down because of a temperature increase. Its particles are moving apart due to repulsion between them.
