Question

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 57.3 degrees. Low Temperature (0F) | 40 – 44 45-49 50-54 55-59 60-64 2 Frequency 3 - 7 11 6 3 degrees. The mean of the frequency distribution is (Round to the nearest tenth as needed.) Which of the following best describes the relationship between the computed mean and the actual mean? O A. The computed mean is close to the actual mean because the difference between the means is more than 5% of the actual mean. OB. The computed mean is not close to the actual mean because the difference between the means is more than 5% of the actual mean. O C. The computed mean is not close to the actual mean because the difference between the means is less than 5% of the actual mean. D. The computed mean is close to the actual mean because the difference between the means is less than 5% of the actual mean.

Answer 1

The statistical software output for this problem is :

Approximate summary statistics:
Using counts in F

Column	Mean
L T	51.833333

Mean = 51.8 degrees

Option D) is correct
