O Ho is rejected. There is sufficient evidence to indicate a difference in mean CPK values for runners before and after exercise. O Ho is not rejected. There is insufficient evidence to indicate a difference in mean CPK values for runners before and after exercise. O Ho is not rejected. There is sufficient evidence to indicate a difference in mean CPK values for runners before and after exercise. O Ho is rejected. There is insufficient evidence to indicate a difference in mean CPK values for runners before and after exercise. (d) Find a 95% confidence interval estimate for the difference in mean CPK values (in units/L) for cyclists before and after exercise. (Use /1 - M2, with /j for after exercise and u2 for before exercise. Round your answers to three decimal places.) units/L to |units/L Does your estimate indicate that there is no significant difference in mean CPK levels for cyclists before and after exercise? O Since the interval contains the value (/1 - #2) = 0, we cannot conclude that there is a significant difference between the means. Since the interval does not contain the value (/1 - /2) = 0, we cannot conclude that there is a significant difference between the means. Since the interval contains the value (M1 - #2) = 0, we can conclude that there is a significant difference between the means. Since the interval does not contain the value (M1 - /2) = 0, we can conclude that there is a significant difference between the means.
