Researchers wanted to know if living in schools protects minnows from predators. The researchers placed different numbers of minnows into separate aquaria. Then, the researchers counted how many times per minute predatory fish approached the schools. Calculate the sample means, ?¯,x¯, and sample standard deviations, ?,s, for the number of times per minute a predator approached each school size. Round ?¯x¯ to one decimal place. Round ?s to two decimal places. Minnow school size Trial 3 5 10 15 20 1 0.9 0.7 0.4 0.4 0.1 2 0.8 0.8 0.5 0.5 0.1 3 0.7 0.9 0.6 0.3 0.2 4 1.1 0.6 0.8 0.2 0.3 5 1.0 1.0 0.7 0.6 0.3
