A psychologist is interested in constructing a 95% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. 53 of the 840 randomly selected people who were surveyed agreed with this theory. a. With 95% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is between and b. If many groups of 840 randomly selected people are surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain and about percent will not contain the true population proportion.

A researcher is curious about whether there is a relationship between how much a person enjoys the music of Nickelback (on a 0-12 scale, 0 indicating no enjoyment and 20 indicating maximum enjoyment) and how much a person enjoys films starring Nicolas Cage (on the same 0-20 scale). The following information was gathered from 10 participants:   Nickelback Nicolas Cage 4 7 12 7 6 6 19 15 0 12 5 9 2 1 13 10 16 20 1 8   Make a scatter diagram: Based on the scatter diagram you made, what type of correlation do you assume?   Question 9Select one: a.

In a survey of families in which both parents work, one of the questions asked was, “Have you refused a job, promotion, or transfer because it would mean less time with your family?” A total of 200 men and 200 women were asked this question. “Yes” was the response given by 29% of the men and 24% of the women. Based on this survey, can we conclude that there is a difference in the proportion of men and women responding “yes” at the 0.05 level of significance?

You may need to use the appropriate appendix table or technology to answer this question. A national standardized test consists of three parts: critical reading, mathematics, and writing. Suppose each part of the test is scored on a 200- to 800-point scale with a median of approximately 510. Scores for each part of the test can be assumed to be symmetric. Use the following data to test the hypothesis that the population median score for the students taking the writing portion of the test is 510. 635 701 439 447 464 502 405 453 471 476 447 590 337 387 514 State the null and alternative hypotheses. O Ho: Median # 510 H₂: Median = 510 O Ho: Median 2 510 H₂: Median 510 ✓ Find the value of the test statistic. T = Find the p-value. (Round your answer to four decimal places.) p-value = Using a = 0.05, what is your conclusion? O Reject Ho. There is sufficient evidence to conclude that the population median writing test score is not 510. Ⓒ Do not reject Ho. There is not sufficient evidence to…
