This is bird migration time. An ornithologist measures the weight of samples of Canada Geese. He takes 81 samples with a mean of 1.5 kg and a standard deviation of 0.75 kg. What weight would put a sample in the top 5% by weight? Answer to three decimal places (don’t include the kg, just the number)

Shouldn't we be using a t score? We don't have the population standard deviation and are left to work with the sample standard deviation. Is the next sample, the one we need to estimate if it's in the top 5%, also of size 81?
