Question

question 5 of 10
the frequency table shows the results of a survey asking people how many hours they spend online per week. on a piece of paper, draw a histogram to represent the data. then determine which answer choice matches the histogram you drew.

hours online	frequency
4-7	8
8-11	10
12-15	8
16-19	7

a. histogram a

b. histogram b

c. histogram c

d. histogram d

Explanation:

Step1: Analyze 0-3 hours

Frequency is 5, so the bar height should match 5 on the y - axis.

Step2: Analyze 4 - 7 hours

Frequency is 8, so the bar height should match 8 on the y - axis.

Step3: Analyze 8 - 11 hours

Frequency is 10, so the bar height should match 10 on the y - axis.

Step4: Analyze 12 - 15 hours

Frequency is 8, so the bar height should match 8 on the y - axis.

Step5: Analyze 16 - 19 hours

Frequency is 7, so the bar height should match 7 on the y - axis.
Now, check each option:

• Option A: 12 - 15 bar height is 8? Wait, no, in A, 12 - 15 and 4 - 7 are same? Wait, no, let's re - check. Wait, 0 - 3:5, 4 - 7:8, 8 - 11:10, 12 - 15:8, 16 - 19:7.

Looking at option D: 0 - 3 (5), 4 - 7 (8), 8 - 11 (10), 12 - 15 (8), 16 - 19 (7). Yes, that matches. Wait, wait, let's check the graphs again. Wait, the y - axis has 0 - 12. Let's check the heights:

• 0 - 3: height up to 5 (correct for frequency 5)
• 4 - 7: height up to 8 (correct for frequency 8)
• 8 - 11: height up to 10 (correct for frequency 10)
• 12 - 15: height up to 8 (correct for frequency 8)
• 16 - 19: height up to 7 (correct for frequency 7)

Looking at the options, option D has these heights. Wait, let's check the options again. Wait, maybe I made a mistake. Wait, the 12 - 15 in option D: is it 8? And 16 - 19 is 7. Yes. Let's check option A: 12 - 15 and 4 - 7 same? No, 4 - 7 is 8, 12 - 15 in A: is it 8? Wait, no, in option A, 12 - 15 and 4 - 7 are same? Wait, the blue bars (maybe the filled ones? Wait, no, the orange and blue? Wait, maybe the non - striped are the ones we need? Wait, no, the histogram has bars for each interval. Let's re - express the frequencies:

Interval 0 - 3: frequency 5

Interval 4 - 7: frequency 8

Interval 8 - 11: frequency 10

Interval 12 - 15: frequency 8

Interval 16 - 19: frequency 7

Now, let's check the height of each bar in the options:

• For 0 - 3: height = 5

• 4 - 7: height = 8

• 8 - 11: height = 10

• 12 - 15: height = 8

• 16 - 19: height = 7

Now, looking at the options:

Option D:

• 0 - 3: height ~5

• 4 - 7: height ~8

• 8 - 11: height ~10

• 12 - 15: height ~8

• 16 - 19: height ~7

Yes, that's correct. So the correct option is D.

Answer:

D. Hours online graph (the one labeled D with 0 - 3:5, 4 - 7:8, 8 - 11:10, 12 - 15:8, 16 - 19:7 bar heights)
