3. Take the mean and standard deviation of data set A calculatedin problem 1 and assume that they are population parameters (Î¼ andÏƒ) known for the variable fish length in a population of rainbowtrouts in the Coldwater River. Imagine that data set B is a sampleobtained from a different population in Red River (Chapter 6problem!). a) Conduct a hypothesis test to see if the mean fishlength in the Red River population is different from the populationin Coldwater River. b) Conduct a hypothesis test to see if thevariance in fish length is different in the Red River populationcompared to the variance in the Coldwater population.
â€¢ Data set A: total= 677.98, mean= 67.798, n= 10, variance=0.663084, std devition= 0.814299972
â€¢ Data set B: total= 574.24, mean=71.78, n=8, variance=0.727143, std devition= 0.852726719
