uiz: Ch 3 Quiz Time Remaining: 00 5 is Question: 1 pt 2015(0 complete) This Q Find the mean of the data summarized in the given frequency distribution Compare the computed mean to Speed (miles per hour) Frequency the actual mean of 468 miles per hour 42-45 24 46-49 15 50-53 54-57 58-61 The mean of the frequency distribution is miles per hour (Round to the nearest tenth as needed.) Which of the following best ascribes the relationship between the computed mean and the actual mean? O A. The computed mean is cose to the actual mean because the amerence between the means is less tan 5% B. O c. O D. The computed mean is close to the actual mean because the dimerence between the means is more than 5%. The computed mean is not cose to the actual mean because the difference between the means is less than 5% The computed mean is not close to the actual mean because the difference between the means is more than 5%.

Explanation / Answer

The statistical software output for this problem is:

Approximate summary statistics:
Using counts in var6

Hence,

Mean of the frequency distribution = 46.9

The computed mean is close to actual mean because the difference is less than 5%.

Option A is correct.

Column Mean var5 46.86
