Some students reported how many pairs of shoes they have. The dot plot shows the data collected:

What do the dots above the number 4 indicate? (3 points)

Question 4 options:

1)

There are exactly 3 students with less than 4 pairs of shoes.

2)

There are exactly 4 students with less than 3 pairs of shoes.

3)

There are exactly 4 students with 3 pairs of shoes.

4)

There are exactly 3 students with 4 pairs of shoes.

True statement : B)there are exactly 4 students with less than 3 pairs of shoes.

Step-by-step explanation:

Complete Question : a dot plot is titled students pairs of shoes and labeled number of pairs. the values on the horizontal line are 1, 2, 3, 4, and 5. there is 1 dot above 1, 3 dots above 2, 5 dots above 3, 3 dots above 4, and 1 dot above 5.  what do the dots above the number 4 indicate?

A)there are exactly 3 students with less than 4 pairs of shoes.

B)there are exactly 4 students with less than 3 pairs of shoes.

C)there are exactly 4 students with 3 pairs of shoes.

D)there are exactly 3 students with 4 pairs of shoes.

From the question we have following info:

Pair of shoes     Students

        1                       1

        2                      3

        3                      5

        4                      3

        5                      1

Let's find which statements are true :

A)there are exactly 3 students with less than 4 pairs of shoes.

Pair of shoes less than 4 = Pair 1 + Pair 2 + Pair 3 = 1+3+5 = 9 . So , there are exactly 9 students with less than 4 pairs of shoes. False statement!

B)there are exactly 4 students with less than 3 pairs of shoes.

Pair of shoes less than 3 = Pair 1 + Pair 2 = 1+3 = 4 . So , there are exactly 4 students with less than 3 pairs of shoes . true statement!

C)there are exactly 4 students with 3 pairs of shoes.

Pair of shoes is 3 = Pair 1 + Pair 2 + Pair 3 = 1+3+5 = 9 . So , there are exactly 9 students with 3 pairs of shoes . False statement!

D)there are exactly 3 students with 4 pairs of shoes.

Pair of shoes is 4 = Pair 1 + Pair 2 + Pair 3+ Pair 4 = 1+3+5+3 = 12 . So , there are exactly 12 students with 4 pairs of shoes . False statement!
