We wаnt tо test the hypоthesis thаt the meаn weight оf 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. Find the calculated value of the test statistic needed to compare to the critical value from the table.
