I need help explaining the 95% confidence interval for each model's population (Current & New) mean driving distance and defining the 95% confidence interval for the difference between the means of the two populations. (As listed in the data below)

Lastly, based on this data, do you see a need for larger sample sizes and more testing with the golf balls.

Current New 264 277 261 269 267 263 272 266 258 262 283 251 258 262 266 289 259 286 270 264 263 274 264 266 284 262 263 271 260 260 283 281 255 250 272 263 266 278 268 264 270 272 287 259 289 264 280 280 272 274 275 281 265 276 260 269 278 268 275 262 281 283 274 250 273 253 263 260 275 270 267 263 279 261 274 255 276 263 262 279
