A psychologist is interested in constructing a 99% 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. 68 of the 702 randomly selected people who were surveyed agreed with this theory. Round answers to 4 decimal places where possible. a. With 99% 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 702 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 psychologist is interested in constructing a 99% 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. 60 of the 803 randomly selected people who were surveyed agreed with this theory.

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. 68 of the 725 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 725 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 psychologist is interested in constructing a 90% 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. 57 of the 741 randomly selected people who were surveyed agreed with this theory. a.  With 90% 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 741 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 research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=935 and x=561 who said "yes." Use a 95% confidence level.

Consider two data sets. Set A: n = 5; x = 4    Set B: n = 50; x = 4 (a) Suppose the number 26 is included as an additional data value in Set A. Compute x for the new data set. Hint:         x = nx. To compute x for the new data set, add 26 to         x of the original data set and divide by 6. (Round your answer to two decimal places.) (b) Suppose the number 26 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.)

Suppose you calculate a 95% and 90% confidence interval for the true proportion of college students with student loan using the same data set. Which of the following must be true? a) The 95% confidence interval is wider than the 90% confidence interval. b) The 95% confidence interval is the same length as the 90% confidence interval. c) The 95% confidence interval is narrower than the 90% confidence interval. d) There is no way to tell from the given information.

Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)

A psychologist is interested in constructing a 99% 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. 56 of the 700 randomly selected people who were surveyed agreed with this theory. Round answers to 4 decimal places where possible. a.  With 99% 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 700 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.

How would a 90​% interval compare with the others in​ width?   A. A 90​% interval would be narrower than the 95​% confidence interval but wider than the 80​% confidence because intervals get narrower with increasing confidence level.   B. A 90​% interval would be wider than the 95​% confidence interval but narrower than the 80​% confidence because intervals get narrower with increasing confidence level   C. A 90​% interval would be wider than the 95​% confidence interval but narrower than the 80​% confidence because intervals get wider with increasing confidence level.   D. A 90​% interval would be narrower than the 95​% confidence interval but wider than the 80​% confidence because intervals get wider with increasing confidence level.
