(a)

Explanation of Solution
Given Information:The table below shows the number of gold medals won by United States Olympic team at the Summer Olympics from
Scatter plot:
To plot the scatter diagram for the given data, take years on X- Axis and number of medals on the Y- axis and point the given points as shown below.
Scatter plot for the given data.
(b)
To conclude:The objective is to draw the conclusion about the relationship depicted in the data.
(b)

Explanation of Solution
Given Information: The scatter plot is given
The graph has neither the positive nor the
All the points are scattered therefore, no concrete conclusion about the relationship between the number of medals and year can be made.
(c)
To find: if it is possible to predict the number of gold medals that can be won in
(c)

Explanation of Solution
Given Information: The scatter plot is given
Th points are all scattered and no concrete conclusion about the relationship between the number of medals and year can be made.
Therefore, it is not possible to predict the number of gold medals that will be won in
