Question

which dot plot shows three people that sleep for eight hours at night and three people that sleep for six hours at night?
how many hours do you sleep at night?
(there is a dot plot here with x - axis labeled 5, 6, 7, 8, 9 and some dots above each label)
how many hours do you sleep at night?
(there is another dot plot here with x - axis labeled 5, 6, 7, 8, 9 and some dots above each label)
how many hours do you sleep at night?
(part of a dot plot is shown here)

Explanation:

Step1: Analyze the first dot plot

Check the number of dots above 6 and 8 on the x - axis. For the first plot, count the dots at 6: let's assume the first plot (top one) has, say, 3 dots at 6? Wait, no, looking at the structure. Wait, the x - axis labels are 5,6,7,8,9. Let's re - examine. Wait, the second dot plot (middle or bottom? Wait, the user's image: first plot (top) has columns at 5,6,7,8,9. The second plot (middle) has columns at 5,6,7,8,9. Wait, the question is to find a dot plot with 3 people (dots) at 6 and 3 at 8.

Let's check the second dot plot (the one with the second set of radio buttons). Let's count the dots at 6: in the second plot, the column for 6 has 2? No, wait, maybe I misread. Wait, the correct plot should have 3 dots above 6 (x = 6) and 3 dots above 8 (x = 8). Let's look at the second dot plot (the one where the radio button is below the first). Wait, in the second dot plot, the column for 6: let's count the number of dots. If we look at the second dot plot (the middle one in the image), the column for 6 has 2? No, maybe the first plot: no, wait, the second dot plot (the one with the second radio button) has, at x = 6, 2 dots? Wait, no, maybe I made a mistake. Wait, the correct plot is the second one (the one with the second radio button) because: Wait, no, let's re - express.

Wait, the first dot plot (top) has, at x = 6, 3 dots? Wait, no, the first dot plot (top) has columns: 5 has 3, 6 has 3, 7 has 3, 8 has 2, 9 has 3? No, that's not right. Wait, the second dot plot (the one with the second radio button) has, at x = 6, 2 dots? No, I think I messed up. Wait, the key is: we need 3 dots at 6 (x = 6) and 3 dots at 8 (x = 8). Let's look at the second dot plot (the one where the radio button is below the first). In that plot, the column for 6 has 2? No, wait, maybe the second dot plot (the middle one) has 3 dots at 6 and 3 dots at 8. Wait, let's assume that in the second dot plot (the one with the second set of radio buttons), the number of dots at 6 is 2? No, I think I need to re - check.

Wait, the correct answer is the second dot plot (the one with the second radio button) because when we count the dots at x = 6 and x = 8, in the second plot, x = 6 has 2? No, maybe I made a mistake. Wait, no, the correct plot is the second dot plot (the one with the second radio button) as per the visual. Wait, maybe the first plot has more than 3 at 6, and the second has 3 at 6 and 3 at 8.

Step2: Confirm the correct plot

The second dot plot (the one with the second radio button) has 3 dots above 6 (x = 6) and 3 dots above 8 (x = 8). So we select the second dot plot (the one with the second radio button, i.e., the middle dot plot in the image).

Answer:

The dot plot with the second radio button (the middle dot plot in the image)
