You collect 53 samples of hair from baby river otters and find that they are, on average, 22.6 mm long, with a standard devaition of 15.2mm.
Then you collect 41 samples of hair from baby sea otters and find that they are, on average, 26.4 mm long, with a standard deviation of 11.4 mm.
Is there statistical evidence at the 0.05 significance level that the true mean of baby sea otter hair length exceeds the true mean of baby river otter hair length by more than 3 mm? Use a test of your choice.

1. A hypothetical investigation on rider satisfaction with a particular public transit system serving commuting residents of British California (BC) and Prince Edward’s County (PEC) offers some interesting findings. The proportion of commuters from BC that indicated low satisfaction with the transit system’s service in the 2018 calendar year was 65 percent, and the proportion from PEC was 70 percent. These point estimates were based on samples of 5,380 BC commuters and 6,810 PEC commuters, whose system-using commuters number in...
