What was the age distribution of prehistoric Native Americans? Extensive anthropological studies in the southwestern United States gave the following information about a prehistoric extended family group of 84 members on what is now a Native American reservation. For this community, estimate the mean age expressed in years, the sample variance, and the sample standard deviation. For the ciass 31 and over, use 35.5 as the class midpoint. (Round your answers to one decimal place.) Age range (years) Number of individuals 1-10 11-20 19 21-30 15 31 and over 40 10
