Question

section ii reading and interpreting graphs
21 a study was done for a vitamin supplement that claims to shorten the length of the common cold. the data the scientists collected from ten patients in an early study are shown in the table below.

number of months taking supplement	0.5	2.5	1	2	0.5	1	2	1	1.5	2.5
number of days cold lasted	4.5	1.6	3	1.8	5	4.2	2.4	3.6	3.3	1.4

a. create a scatter - plot. remember: x - axis the independent variable and the y - axis represents the dependent variable.

Explanation:

Step1: Identify variables

The number of months taking supplement is the independent variable (x - values) and the number of days cold lasted is the dependent variable (y - values).

Step2: Plot points

For each pair of values in the table, plot a point on the coordinate - plane. For example, for the first pair (0.5, 4.5), we go 0.5 units along the x - axis and 4.5 units up along the y - axis and mark a point. Repeat this for all pairs: (2.5, 1.6), (1, 3), (2, 1.8), (0.5, 5), (1, 4.2), (2, 2.4), (1, 3.6), (1.5, 3.3), (2.5, 1.4).

Since this is a task of creating a scatter - plot and not providing a numerical answer, we can't give a single numerical "answer" in the traditional sense. But the steps above describe how to create the scatter - plot. If we were to summarize the result of the task, we could say:

Answer:

A scatter - plot with points plotted according to the pairs of (number of months taking supplement, number of days cold lasted) values from the table.
