- A market researcher collects a simple random sample of customers from a population of over a million customers that use a home improvement website. After analyzing the sample, she states that she has 95% confidence that the mean time customers spent on that website per day is between 17 and 54 minutes. Suppose that the population mean time customers spent on that website is 14 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain. Question content area bottom Part 1 Choose the correct answer below. A. No, because the population mean, μ, is not the midpoint of the confidence interval estimate. B. Yes, because the population mean, μ is within 95% of the midpoint of the confidence interval estimate. C. No, because the population mean, μ, is not included within the confidence interval estimate. D. Yes, because the population mean, μ, is relatively close to the…A biologist is studying fish diversity Lake Erie. The biologist knows that Black Carp are an invasive species in the region and would like to estimate the proportion of fish in Lake Erie that are Black Carp.

- You plan to conduct a survey to find out the proportion of students who enjoy taking classes remotely. You have no idea what proportion to expect from your study but you know you want to create a 90% confidence interval with a margin of error of 2%. What sample size should you use? Show your work on paperYou are working as an assistant to the dean of institutional research at your university. The dean wants to survey members of the alumni association who obtained their baccalaureate degrees 5 years ago to learn what their starting salaries were in their first full-time job after receiving their degrees. A sample of 100 alumni is to be randomly selected from the list of 1,200 graduates in that class. If the dean's goal is to construct a 95% confidence interval estimate for the population mean starting salary, why is it not possible that you will be able to use the expression X±Z0.025σn for this purpose? Explain. Question content area bottom Part 1 Why is it not possible to use the equation? A. The sample size n is not large enough to use this expression. B. The sample mean X might not be a whole number, but the number of students must be. C. The population standard deviation σ is not known. D. The sample size n is too large to use this…A professor at a large university believes that students take an average of 16 credit hours per term.
