Scott Brim, Chief Financial Officer of Space Mall, Inc., wants to better understand the biest business hours during the weekend. There are door sensors that approximately count the number of people who enter the mall. The table below presents the average number of people coming in during the weekend, for the last month:  
The relative frequency of the fourth class interval is ___.

Quizplus · Accepted Answer

The fourth class interval is 12-under 1, with an average of 650 people. To find the relative frequency, we need to divide the frequency of this interval (650) by the total number of people counted during the weekend (sum of all frequencies, which is 4000).

Relative frequency = 650/4000 = 0.1625

However, we need to round this value to two decimal places:

Relative frequency = 0.16

Looking at the answer choices, the closest option is C) 0.14, which is the relative frequency for the third class interval (11-under 12). Therefore, the best choice is C because it is the closest option to the actual relative frequency for the fourth class interval.
