(5) Use StatKey to generate 2000 bootstrap samples, and sketch the dotplot of the bootstrap distribution. You may draw vertical lines instead of dots in your sketch. What is the mean of your bootstrap distribution, and how does it compare to the original sample mean? Instructions: Go to StatKey and click "CI for Single Mean, Median, Std. Dev." Click "Edit Data," delete all of the numbers, and type the 10 textbook prices (one on each line). Click "Generate 1000 Samples" twice. (6) Use your dotplot and the 95% rule to estimate a 95% confidence interval for the mean price of all textbooks. List 5 plausible values for the mean price of all textbooks, based on your confidence interval.

Question
Please show work on paper and circle answer and only do Question 4,5 and 6
Prices of a random sample of 10 textbooks (rounded to the nearest dollar) are shown here: $132 $87 $185 $52 $23 $147 $125 $93 $85 $72 (1) Write the prices on 10 small notecards or strips of paper, with one price on each card. (2) Use your 10 cards to generate a bootstrap sample, and record the results here. (3) Calculate the mean of the bootstrap sample, using correct notation. (4) Use your 10 cards to generate 9 more bootstrap samples, for a total of 10 bootstrap samples. Record the results here, and calculate the mean of each bootstrap sample.
