A clinic compared healthy dogs it owned with healthy pets brought to clinic to be neutered. The summary statistics for blood cholesterol levels (milligrams deciliter of blood) appear in the following table: Types n Average Standard deviation Pets (P) 51 198 69.7 Clinic (C) 51 181 42.9 Difference (d = P - 51 17.0 51.5 C) a) Find a 98% confidence interval for the difference in mean blood cholesterol levels dogs brought to the clinic (P) and dogs owned by the clinic (C). (Round your answers to 4 decimal places, if needed.) b) Based on this confidence interval, can we conclude there is some differences in mean blood cholesterol levels between the two groups? Yes, since the interval contains 0. No, since the interval is completely above 0. Yes, since the interval is completely above 0. No, since the interval contains 0.
