Let’s go step by step to answer each question using the line plot.

First, remember: Each “X” on the line plot represents one student. The number below each X tells us that student’s attendance percentage.

We’ll count the X’s for each attendance value as needed.

---

Question 1: How many students have attendance of 94%?

Look at the column above “94%”. Count the X’s there.

There are 4 X’s above 94%.

→ Answer: 4

---

Question 2: What was the highest attendance in the class?

Look for the rightmost X on the line plot — that’s the highest attendance.

The last X is above 99%.

→ Answer: 99%

---

Question 3: What was the lowest attendance in the class?

Look for the leftmost X on the line plot — that’s the lowest attendance.

The first X is above 85%.

→ Answer: 85%

Question 4: How many students have their attendance in the 80’s?

“80’s” means from 85% to 89% (since the plot starts at 85%).

Count all X’s above:

- 85% → 5 X’s
- 86% → 2 X’s
- 87% → 6 X’s
- 88% → 1 X
- 89% → 0 X’s

Add them: 5 + 2 + 6 + 1 = 14

→ Answer: 14

---

Question 5: How many students have their attendance in the 90’s?

“90’s” means from 90% to 99%. But note: 90% and 91% have no X’s? Let’s check:

Actually, looking again:

- 90% → 0
- 91% → 2 X’s
- 92% → 3 X’s
- 93% → 0
- 94% → 4 X’s
- 95% → 0
- 96% → 3 X’s
- 97% → 2 X’s
- 98% → 5 X’s
- 99% → 1 X

Wait — let me recount carefully from the plot:

From the image description (and standard interpretation):

At 91%: 2 X’s
At 92%: 3 X’s
At 94%: 4 X’s
At 96%: 3 X’s
At 97%: 2 X’s
At 98%: 5 X’s
At 99%: 1 X

(90%, 93%, 95% have zero)

So add: 2 + 3 + 4 + 3 + 2 + 5 + 1 = 20

→ Answer: 20

---

Question 6: How many students have attendance of 93% or less?

That means all students with attendance from 85% up to and including 93%.

Break it down:

85%: 5
86%: 2
87%: 6
88%: 1
89%: 0
90%: 0
91%: 2
92%: 3
93%: 0

Add: 5+2=7; 7+6=13; 13+1=14; 14+0=14; 14+0=14; 14+2=16; 16+3=19; 19+0=19

→ Answer: 19

---

Question 7: How many students are there in the class?

This is the total number of X’s on the entire plot.

We can add all the counts we’ve done so far, or do a full count.

Let’s list every attendance value and its count:

85%: 5
86%: 2
87%: 6
88%: 1
89%: 0
90%: 0
91%: 2
92%: 3
93%: 0
94%: 4
95%: 0
96%: 3
97%: 2
98%: 5
99%: 1
100%: 0 (no X shown)

Now add:

Start with 85–89: 5+2+6+1 = 14
Then 90–93: 0+2+3+0 = 5 → total so far: 19
Then 94–99: 4+0+3+2+5+1 = 15 → total: 19 + 15 = 34

Double-check:

List all numbers:

5 (85)
+2 (86) = 7
+6 (87) = 13
+1 (88) = 14
+0 (89) = 14
+0 (90) = 14
+2 (91) = 16
+3 (92) = 19
+0 (93) = 19
+4 (94) = 23
+0 (95) = 23
+3 (96) = 26
+2 (97) = 28
+5 (98) = 33
+1 (99) = 34

Yes, total = 34

→ Answer: 34

Final Answer:
1. 4
2. 99%
3. 85%
4. 14
5. 20
6. 19
7. 34
