Question

The data represents the number of ounces of water that 26 students drink before donating blood: 8, 8, 8, 16, 16, 16, 32, 32, 32, 32, 32, 32, 64, 64 64,64, 64,64,64,80,80,80,88,88,88. Create a dot plot for the data.

Answer 1

See Explanation

Explanation:

The data give is for 25 students not 26 as stated in the question

First, we need to plot the frequency table:

This is done as follows:

Ounces of Water ----- Frequency

8 ----------------------------- 3

16 ----------------------------- 3

32 ---------------------------- 6

64 --------------------------- 7

80 ----------------------------- 3

88 ----------------------------- 3

Next, we can now plot the dot plot using an interval of 8 on the x axis

Answer 2

*correct data set given: 8, 8, 8, 16, 16, 16, 32, 32, 32, 32, 32, 32, 64, 64, 64, 64, 64, 64, 64, 80, 80, 80, 80, 88, 88, 88.

Answer:

See attachment

Explanation:

To create a dot plot, first, prepare a tally for the given data set as follows:

Ounces of water => frequency

8 => 3

16 => 3

32 => 6

64 => 7

80 => 4

88 => 3

Next is to draw a scaled horizontal line. This will indicating the number of ounces of water each student drank. The frequency for each will determine how many dot to be plotted against each amount of ounces represented.

A simple dot plot has been created and attached below. Each dot represents the amount of water, in ounces, drank by each of the 26 students.
