7 questions, The prices in dollars for a particular model of camera are shown below for 10 online retailers, statistics homework help
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.

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?

Strayer University Staffing Troubles During Peak Hours Discussions
Wk 5 The manager of a fast-food store realizes that her staffing problems are a result of the variation in the number of customers that arrive at the store. If the same number of customers came each hour, she would know exactly how many servers to have working. It turns out that the Poisson distribution works well to describe the arrivals of customers in any given hour. Explain why the manager has more trouble staffing the store during those hours when the average arrival rate is higher. WK 6 How would you respond to a statement that says that by increasing the sample size, the amount of sampling error will be decreased? Be sure to respond to at least one of your classmates’ posts. Cite any resources used. Wk7 Explain why an increase in sample size will reduce the probability of a Type II error, but will not impact the probability of a Type I error. Support your reasoning using a scholarly source.
