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. 65 of the 732 randomly selected people who were surveyed agreed with this theory. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated...

Out of 500 people sampled, 450 had kids. Based on this, construct a 95% confidence interval for the true population proportion of people with kids. Do not use StatCrunch. Show all formulas used, work and steps. Be sure to define your variables. As in the reading, in your calculations: --Use z = 1.645 for a 90% confidence interval --Use z = 1.96 for a 95% confidence interval --Use z = 2.576 for a 99% confidence interval Give your answer in...

You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 384 randomly selected caterpillars observed, 52 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between and b. If many groups of 384 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About...

2. 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. 64 of the 802 randomly selected people who were surveyed agreed with this theory. 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...

Suppose a 95% confidence interval for the true proportion (p) of people who say they approve of Beto O’Rourke as President is (50%, 58%). One of the below statements is correct, please choose it.The margin of error is plus or minus 1%. There is not enough information to calculate the margin of error. The margin of error is plus or minus 3%. The margin of error is plus or minus 4%.

Question 19 (5 points) A pollster wants to construct a 95% confidence interval for the proportion of adults who believe that economic conditions are getting better. A Gallup poll taken in July 2010 estimates this proportion to be 0.33. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.039? Write only an integer as your answer. Your Answer: Answer Question 20 (5 points) A researcher wants to construct a...

part 1. A student was asked to find a 95% confidence interval for the proportion of students who take notes using data from a random sample of size n = 79. Which of the following is a correct interpretation of the interval 0.12 < p < 0.32? There is a 95% chance that the proportion of notetakers in a sample of 79 students will be between 0.12 and 0.32. There is a 95% chance that the proportion of the population...

what i currently have is wrong...thanks in advance!
A 95% confidence interval for a population proportion was constructed using a sample proportion from a random sample. Which of the following statements are correct? Select all that apply If we were to use a 90% confidence level, the confidence interval from the same data would produce an interval wider than the 95% confidence interval. There is a 95% chance that the 95% confidence interval actually contains the population proportion. We don't...
