A researcher gathered data on hours of video games played by school-aged children and young adults. She collected the following
1 answer:
Step-by-step explanation:
The complete frequency distribution table for the data has been attached to this response.
The frequency column contains values that are the number of times the given range of hours appear in the data. For example, numbers in the range 0 - 2 hours, appear <em>9</em> times in the data. Also, the numbers in the range 3 - 5 appear <em>6</em> times. The same logic applies to other ranges.
The relative frequency column contains the ratio of the number of times the given range of hours appear in the data, to the total number of outcomes. The total number of outcomes is the sum of all the frequencies on the frequency column. This gives 38 as shown.
So, for example, to get the relative for the numbers in the range 0-2, divide their frequency (9) by the total outcome or frequency (38). i.e
9 / 38 = 0.24
Also, to get the relative for the numbers in the range 3-5, divide their frequency (6) by the total outcome or frequency (38). i.e
6 / 38 = 0.16
Do the same for the other ranges.

Answer:
Diego is correct.
There can be or
groups in 1.
Step-by-step explanation:
From the question statement given we find that we need to divide 1 into groups of .
When we form groups from a given total, we divided the total size by the size of the group.
If we are dividing number of people in groups of
number of people, then the expression to find the number of groups formed can be given as:
⇒
For this question the data given is:
So, the number of groups formed can be given as:
⇒
<em>When divisor is a fraction, then we multiply the reciprocal of the divisor with the dividend.</em>
⇒
⇒
<em>In order to convert fraction to mixed number we will divide numerator with denominator and then write the quotient as whole number, remainder as numerator and the denominator remains as it is.</em>
On dividing 6 by 5, the quotient =1 and remainder =1. Thus the mixed number is:
⇒
Thus, there are or
groups in 1. This matches with Diego's answer and hence he is correct.
