8. The prices in dollars for a particular model of camera are shown below for 10 online retailers. Estimate the true mean price for this particular camera with 95% confidence. Assume normal distribution. 225, 240, 215, 206, 211, 210, 193, 250, 225, 202. Please round to the nearest tenth and write your answer in the form ( , ); for example (31,34) or (25,46). Do not type in any extra spaces.9. Assume that we want to construct a confidence interval. Determine whether you should use the t-distribution or the normal distribution to find it, based off of the following information. In this problem, let n be the sample size. n = 23, the standard deviation is unknown, the population appears to be normally distributedo T-Distributiono Normal Distributiono neither of the methods studied by us can be used10. Assume that we want to construct a confidence interval. Determine whether you should use the t-distribution or the normal distribution to find it, based off of the following information. In this problem, let n be the sample size.n = 200, the standard deviation is 15, the population appears to be skewedT-DistributionNormal Distributionneither of the methods studied by us can be used11. Assume that we want to construct a confidence interval. Determine whether you should use the t-distribution or the normal distribution to find it, based off of the following information. In this problem, let n be the sample size.n = 5, the standard deviation is known, the population appears to be very skewed neither of the methods studied by us can be used Normal Distribution t-distribution12. Assume that we want to construct a confidence interval. Determine whether you should use the t-distribution or the normal distribution to find it, based off of the following information. In this problem, let n be the sample size n = 200, the standard deviation is unknown, the population appears to be normally distributed T-Distribution Normal Distribution13. A university of dean of students wishes to estimate the average number of hours students spend doing homework per week. The standard deviation from a previous study is 6.2 hours. How large a sample must be selected if he wants to be 99% confident of finding whether the true mean differs from the sample mean by 1.5 hours?14. If the variance of a national accounting examination is 900, how large a sample is needed to estimate the true mean score within 5 points with 99% confidence?

After working for 18 months in your analyst position at G&B Consulting, you are now being considered for a project manager position that would put you in charge of several team members. As part of the interview process, you have been asked to make a presentation to highlight what you think are the most compelling reasons you should get the position. You are to put together a PowerPoint presentation that explains all of the key components that you feel will factor into why you should get the position. What to Submit To complete this assignment, you must first download the word document. Use the questions on the worksheet as your guide for the contents of your presentation. Your step-by-step breakdown of the problems, including explanations and all work shown, should be present within the PowerPoint you create. If you use Excel for any of your calculations that file must also be included in the drop box. Do not submit the Word document with instructions.
