Rodeo officials wanted to compare horse breeds in relation to buck offs before 8 seconds. They compared mustangs to non-mustangs. The 89 mustangs had a mean of 45 with a standard deviation of 2. The 61 non-mustang bred horses had a mean of 12 with a standard deviation of 1.5. Is the mean number for mustang-bred horses significantly higher than those that were not mustang bred?
