Find the mean of the data summarized in the given frequency distance distributio

Question

Find the mean of the data summarized in the given frequency distance distribution. Compare the computed mean to the actual mean of 5.15 degrees The mean of the frequency distribution is degrees. (Round to the nearest tenth at needed.) Which of the Mowing best describes the relationship between the computed mean and the actual mean? A. The computed mean is dose to the actual mean because the difference between the means is less than 5%. B The computed mean is close to the actual mean because the difference between the means is more than 5%. C The computed mean is not 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%.

Explanation / Answer

Solution:-
The mean of the frequency distribution is 51.17 miles per hour.

[(2 x 42) + (7 x 47) + (9 x 52) + (5 x 57) + (1 x 62)] ÷ 24 = 51.17

=> option A.   The computed mean is close to the actual mean because the difference between the means is less than 5%.
