Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 51.4 miles per hour. Speed (miles per hour) 42 -45 46-49 50 -53 54-57 58-61 Frequency 28 14 6 3 The mean of the frequency distribution is miles per hour. Round to the nearest tenth as needed.) Which of the following best discribes the relationship between the computed mean and the actual mean? A. The computed mean is close to the actual mean because the difference between the means is less than 5% O B. The computed mean is not close to the actual mean because the difference between the means is more than 5% O C. The computed mean is close to the actual mean because the difference between the means is more than 5%. @) D. The computed mean is not close to the actual mean because the difference between the means is less than 5%
