- Students at a certain college were asked if they have a car. After surveying 1692 students, it was found that 24.8% of them have a car. The margin of error was 2.1% with a 95% confidence level. What does this margin of error tell you about the percentage of students at that college who have a car? We can be 95% confident that somewhere between ?% and ?% of the students at that college have a car.2) Estimate the difference between the ages of male and female respondents with 95% confidence.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. 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 803 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.

- Suppose that the coach from Question 3 decides he wants to be more confident. The coach uses the same sample data as before, but recalculates the confidence interval using a 99% confidence level. How will increasing the confidence level from 95% to 99% affect the confidence interval? A B с D It is impossible to say without seeing the sample data. Increasing the confidence will increase the margin of error resulting in a wider interval. Increasing the confidence will decrease the margin of error resulting in a narrower interval. Increasing the confidence will have no effect on the interval.Is the proportion of wildfires caused by humans in the south different from the proportion of wildfires caused by humans in the west? 350 of the 519 randomly selected wildfires looked at in the south were caused by humans while 383 of the 500 randomly selected wildfires looked at the west were caused by humans.
