Question

Take the mean and standard deviation of data set A calculated in problem 1 and assume that they are population parameters (μ and σ) known for the variable fish length in a population of rainbow trouts in the Coldwater River. Imagine that data set B is a sample obtained from a different population in Red River (Chapter 6 problem!).

1. Conduct a hypothesis test to see if the mean fish length in the Red River population is different from the population in Coldwater River.

2. Conduct a hypothesis test to see if the variance in fish length is different in the Red River population compared to the variance in the Coldwater population.

Data A: 8.23,8.33,8.25,8.16,8.03, 8.03, 8.10, 8.11, 8.25, 8.25, 8.23

Data B: 8.84, 8.70, 8.10, 8.20, 8.23, 8.18, 8.23, 8.34, 8.29

Please show all the detailed work, thank you in advance.
