Fоllоwing аre the published weights (in pоunds) of аll of the teаm members of the San Francisco 49ers from a previous year: 170; 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. Then determine whether the distribution is normal, right-skewed or left-skewed. Find the percentile (rank) of 270. 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. Emmit Smith, who played for the Dallas Cowboys, weighed in at 209 pounds. Find the z-scores of Smith and Young and determine who is the relatively lighter player, Smith or Young? Formula:
