Assume that the weights of salmon in the Columbia River are normally distributed. You randomly catch and weigh 20 salmon. The mean weight from your sample is x ̄ = 25.2 pounds with a standard deviation of s = 4.5 pounds. Test the claim that the mean weight of Columbia River salmon is greater than 23 pounds. Use a α = 0.10 significance level. 

Question: What hypothesis test should you use for this problem?

1.     Mean-1 Sample 

2.     Mean-2 Samples, Dependent 

3.     Mean-2 Samples, Independent

4.     Proportion-1 Sample 

5.     Proportion-2 Samples
