The weights of a type of fish in a lake are approximately normal with a mean of 2.5 pounds and a standard deviation of 0.3 pounds. Use stat key (lock5stat.com) to answer the following 2 parts (blanks). On your scrap/work sheet, sketch the stat key display to support your answer for submission after the test. Just type your answers in on this online test. Part/Blank 1: What proportion of the fish weigh more than 3 pounds? Give all the decimal digits stat key displays. Part/Blank 2: Find the weight that would represent the 10th percentile of fish weights. (give all the digits stat key shows and include the unit of measure for this value)

Type in a short answer for each of these prompts: Blank 1/Part 1: Where is a sampling distribution for a sample mean centered? (assuming a good random sampling plan)? (use this scenario to answer parts/blanks 2 and 3 below) An employee at a bolt manufacturing company wanted to construct a confidence interval estimate for the population proportion of their bolts that had a groove imperfection. They obtained a sample proportion of 0.12 and calculated a margin of error of 0.04 at a 90% confidence level. Blank 2/Part 2: What would be the point estimate (or best guess) for the population mean? Blank 3/Part 3: What would be the resulting confidence interval?

Mr. Reid collected a small random sample of students on campus at SUNY Broome and for each student recorded the number of siblings they have. The original sample was {0, 1, 1, 2, 3, 5}. Blank 1/Part 1: Yes or no: could {0, 0, 0, 1, 1, 1} be a bootstrap sample taken from this original? Blank 2/Part 2: Why couldn’t {0, 1, 2, 3, 5} be a bootstrap sample in this situation? Blank 3/Part 3: Why couldn’t {0, 1, 1, 4, 5, 5} be a bootstrap sample in this situation?
