Question USE THE GRAPH’S BELOW Questions for Task 1: 1)What is the sample… USE THE GRAPH’S BELOW Questions for Task 1: 1)What is the sample mean of our original sample? The mean of the original sample is 15.98 = $15,980. 2) What characteristics of the original sample make it NOT appropriate for us to use a t procedure to make our confidence interval? 3)What is the standard deviation of your bootstrap distribution, i.e., the standard error? 4) Using your answers above, what is your 95% confidence interval for µ? 5) Given your confidence interval, would you reject a claim that µ = $21,000, or would you fail to reject a claim that µ = $21,000. Carefully explain your reasoning and reference your interval in your explanation for full credit. 6) Imagine that a friend of yours who lives in the area is preparing to sell a Ford Mustang and they ask you to help them determine a selling price. Please create a message that starts with “Dear friend,” and includes two or more sentences that include the following: the selling price you recommend, some background as to how this StatKey exercise helped you come up with that price, any additional information you would like to have from your friend about the car that might lead you to change your recommend price number, and some advice to your friend as to where they could look for more information about pricing the car. 7) Submit a single screen print of your StatKey screen that shows your bootstrap distribution, a dotplot of the original sample, and the summary measures for both.

Explain your reasoning and reference your p-value in youexplanation for full credit. You can use a significance level of á = .05 if you wish. 5) Submit a single screen print of your StatKey screen that shows your randomization distribution, your p-value and the corresponding highlighted portion of the randomization distribution used to compute the p-value, a dotplot of the original samples, and the difference of the sample means.
