3.A biologist claims that the average weight of the fish in Lake Ontario is at least 2.5 kg. To test his claim, we randomly catch 50 fish from the lake and note that their average weight is 2.4 kg. From other research, we know that the standard deviation of the weight of the fish in Lake Ontario is 120 grams. Use the 7 steps and conduct a hypothesis test for the biologist's claim using the critical value method at the significance level of 5%. Note: make sure both mean and standard deviation have the same unit. 4.Repeat Steps 5 and 6 of Question 3 using the P-value method
