Answer:

The correct answer is:

$12.00 and up to $15.00 (D)

Explanation:

Let us arrange the data properly in a tabular format.

Hourly Earnings($) 6 - 9 9 - 12 12 - 15

Frequency 16 42 10

The frequency of a distribution is the number of times that distribution occurs in a particular group of data or intervals.

From the frequency table above the following observations can be made:

Highest frequency = 42 (hourly earnings of $9 - $12)

smallest frequency = 10 ( hourly earnings of $12 - $15)

This means that among a total of 68 workers (16 + 42 + 10), the people earning $12 - $15 form the smallest group (only 10 people), while 42 workers earn $9 - $12, forming the largest majority
