We want to test the hypothesis that the mean weight of a breed of dogs is greater than 40 lb. Therefore, we obtain the weights of a random sample of 36 dogs. The dogs in the sample weighed an average of 43 lb with a standard deviation of 6 lb. We want to test: Ho: μ = 40 lb Ha: μ > 40 lb using a significance level (α) = 0.05. Should we reject Ho: μ = 40 lb? Explain.
