A personal trainer determines that an individual will get the most benefit from a workout if they keep their heart rate at an average of 150 beats per minute during workouts. To determine if the individual is doing so successfully, a random sample of 30 workouts is selected from their fitness watch. A 95% confidence interval for these workouts reveals that the true mean heart rate while working out is between 158 and 167 beats per minute. Based upon this interval, what conclusion should be made about the hypotheses: Ho = 150 versus H 150 where u = this individual's true mean heart rate during working out at a = 0.05? Reject Ho. There is convincing evidence that the mean heart rate from these 30 workouts differs from 150. Reject Ho. There is convincing evidence that this individual's true mean heart rate while working out differs from 150. Fail to reject Ho. There is not convincing evidence that the mean heart rate from these 30 workouts differs from 150. O Fail to reject Ho.
