Question: Finally, three additional antler samples were uncovered at the Y and Z holes. These holes are part of a formation of concentric circles, 11 meters and 3.7 meters, respectively, outside of the Sarsen Circle. The sample mean age of these antlers is 1671.7 BC with a standard deviation of 99.7 years. Assume that the ages are normally distributed with no obvious outliers. Use an α = 0.05 significance level to test whether the population mean age of the Y and Z holes is different from Corbin's stated mean age of the ditch, that is, 2950 BC.
