The weights (in pounds (lb)) of 52 randomly selected NFL football players are presented below. 305 265 287 285 290 235 300 230 195 236 244 194 190 307 218 315 265 210 194 216 255 300 315 190 185 183 313 246 212 201 308 270 241 242 306 237 315 215 200 295 187 204 257 185 255 318 230 316 200 324 245 185 We would like to construct a 90% confidence interval for the mean weight of NFL football players. Explain why it is not necessary to assess normality for this sample Write an interpretation for your confidence interval, including units if appropriate. You may round the upper and lower limits to the nearest whole number. Does the confidence interval estimate the mean weight for the sample of 52 NFL players or for the population of NFL players? Explain.
