Solution :

Frequency of 5 is 2.

Problem 5 :

A fourth grade class attended a band concert. After the concert, the band conductor asked each student to name their favorite instrument. He recorded the data using tally marks.

Which frequency table represents the number of students that chose each instrument?

Solution :

So, option D is correct.

Problem 6 :

Solution :

So, we will put 15 leaves.

Problem 7 :

Jeri walks her puppy each day. She recorded the distance they walked in the table below.

A) 2    B)  5      C)  3       D)  4

Solution :

In the table, we see the distance walked 3/4 miles 4 times. So, the answer is 4.

Problem 8 :

Keith surveyed the students in his class to find the number of siblings each of them has. The data is shown below.

Keith wants to make a dot plot to represent the data. What data points will be labeled below the number line in the dot plot?

A) 1, 2, 3     B) 1, 2, 3, 4      C)  0, 1, 2      D)  0, 1, 2, 3, 4

Solution :

By observing the table, 5 values are repeated. So, 0, 1, 2, 3, 4, option D is correct.

Problem 9 :

The data shown below represents the number of jumping jacks completed by 15 students in one minute. The physical education teacher is making a stem-and-leaf plot to display the data.

What stems will the teacher put in the stem-and-leaf plot?

A) 0, 3, 4, 5, 9    B) 3, 4, 6   C) 0, 1, 2, 3, 5, 8, 9   D)  3, 4, 5, 6
