Data on pulse rates was collected from a random sample of 100 students from ETSU. We find a 95% confidence interval for mean pulse rate to be (65, 72). Which of the following is the correct interpretation of this interval? The probability is .95 that the mean is in this interval. We are 95% sure that the mean pulse rate for all US college students is between 65 and 72 beats per minute. We are 95% confident that the mean pulse rate for this sample of students will fall between 65 and 72 beats per minute. We are 95% confident that the mean pulse rate of all ETSU students is between 65 and 72 beats per minute. We are 95% sure that all students will have pulse rates between 65 and 72 beats per minute.
