Fоllоwing аre the published weights (in pоunds) of аll of the teаm members of the San Francisco 49ers from a previous year: 174; 177; 178; 184; 185; 185; 188; 190; 200; 205; 205; 206; 210; 210; 212; 212; 215; 215; 220; 223; 228; 230; 232; 241; 241; 242; 245; 247; 250; 250; 259; 260; 260; 265; 265; 270; 272; 273; 275; 276; 280; 280; 280; 280; 285; 285; 286; 290; 290; 295; 302. Find the mean, median, mode and standard deviation, and determine whether the distribution is normal, right-skewed, or left-skewed. Find the percentile (rank) of 259. Round the percentile to the nearest whole number. When Steve Young played for the San Francisco 49ers (data given above) he weighed 205 pounds. That same year, the Dallas Cowboys had a mean weight of 240.1 pounds with a standard deviation of 44.4 pounds. Try Aikman, who played for the Dallas Cowboys, weighed in at 220 pounds. Find the z-scores of Aikman and Young and determine who is the relatively lighter player, Aikman or Young? Formulas:
