Answer:

A: Is the answer of this one

Explanation:

Here is how I found it out it is asking what does it mean with a 50th percent frequency. So first off we see our top two bars 85-89 and 100-114 these are highest so those should not be in our choices. So this would get rid of choices B, C, and D giving us our answer of A.

The sets of IQ scores fall in the bottom 50th percent of frequency is 65-69, 70-84, 115-129, 130-149 So, Option A is correct.

Frequency is defined as the number of times a repetitive occurrence occurs per unit of time. It's also known as high temporal frequency, as opposed to spatial frequency, and ordinary frequency, as opposed to angular frequency.

The other Options are incorrect because:

  • Option B is incorrect as in this set the frequency includes 85-99 which is the second highest in the graph.

  • Option C is incorrect as in this set the frequency includes which are the highest in the graph.

  • Option D is incorrect as in this set the frequency includes which are the highest in the graph.

Thus, Option A is correct because the set includes all the frequency before 50%.
