below for each of the artifacts found at Stonehenge. You will find the mean, the standard deviation and the sample size (n) in the reading in the book. Then complete the confidence interval for each artifact, rounding to the nearest whole number. The last question asks you to determine the order in which the artifacts were constructed, be careful on the order, the time frame is BC so an artifact constructed in 50 BC is newer than an artifact constructed in 100 BC. Unshed antler Mean= Standard deviation = n = Confidence Interval x + tax/2 Vn Animal bones in ditch terminal Mean= Standard deviation = n = Confidence Interval x + tx/2 in Antler, Antler Tine and Animal bone in the concentric circle Mean= Standard deviation = n = Confidence Interval x + tx/2 Vn Antler in the Y and Z holes Mean= Standard deviation = n = Confidence Interval x + tx/2 Vn Based on your findings (from the confidence intervals) what is the order in which they stone monuments were constructed? (from oldest to newest)
