how you recognize when an inferential statistics problem involves either a confidence interval estimate or a hypothesis testing procedure and when it involves either a mean or a proportion.
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 55 minutes. Suppose that the population mean time customers spent on that website is 16 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain. Chood the correct answer below. OA. Yes, because the population mean, u, is relatively close to the confidence interval estimate. OB. Yes, because the population mean, u, is included within the confidence interval estimate. OC. No, because the population mean, u, is not included within the confidence interval estimate. OD. No, because the population mean, u, is not the midpoint of the confidence interval estimate. OE. Yes, because the population mean, uis within 95% of the midpoint of the…
can someone explain how I do this problem? I'm lost and keep messing up, I only have 2 more tries to get it correct, thanks

When calculating confidence interval for a population proportion, what should one use? z-statistic • neither z-statistic nor t-statistic ● t-statistic either z-statistic or t-statistic
A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? The first position is more sensible, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the second position. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. Because we would be interested in any…
Here are some ratings on a scale of 1-10. Use confidence interval of 99% confidence. What is the confidence interval for the population (mean) ? Ratings are: 8, 7, 3, 10, 4, 4, 8, 8, 7, 8, 3, 8.
What z score would be used to calculate the margin of error for a 98% confidence interval for the mean? 2.33 1.75 2.05 correct answer is not given
Working Backwards from the Confidence Interval to Find the Sample MeanSometimes when we read statistical studies, only the confidence interval is stated; however, if the confidence interval is known, we can work backwards to find the sample mean. Suppose a sample mean was used to construct an interval of (42,49). What was the value of the sample mean?
How do I calculate a 90% confidence interval for a sample mean of 15 with a sample standard deviation of 5 and a sample size of 25? I have the answer as 13.29 to 16.71 but I do not know how to get the answer. Please help. Thank you, Denise
