Surfers Surfers and statistics students

Rex Robinson and Sandy Hudson collected data on the number of days on which surfers surfed in the last month for 30 longboard (L) users and 30 short board (S) users. Treat these data as though they were from two independent random samples.

Test the hypothesis that the mean days surfed for all long boarders is larger than the mean days surfed for all short boarders (because longboards can go out in many different surfing conditions).

Use a level of significance of 0.05.

Longboard : 4,9,8,4,8,8,7,9,6,7,10,12,12,10,14,12,15,13,10,11,19,19,14,11,16,19,20,22,20,22.

Short board : 6,4,4,6,8,8,7,9,4,7,8,5,9,8,4,15,12,10,11,12,12,11,14,10,11,13,15,10,20,20.
