3. Take the mean and standard deviation of dataset A calculated in problem 1 and assume that they are populationparameters (μ and σ) known for the variable fish length in apopulation of rainbow trouts in the Coldwater River. Imagine thatdata set B is a sample obtained from a differentpopulation in Red River (Chapter 6 problem!).
- Conduct a hypothesis test to see if the mean fish length in theRed River population is different from the population in ColdwaterRiver.
- Conduct a hypothesis test to see if the variance in fish lengthis different in the Red River population compared to the variancein the Coldwater population.
