Suppose that a stock is worth $5 on October 1 and that its value increases by $3 per week. Let v be the stock’s value (in dollars) at t weeks since October 1.
a. Identify the explanatory and response variables.
b. Construct a table to describe the association between t and v for the following values of t: 0, 1, 2, 3, 4, and 5.
c. Use technology to construct a scatterplot for the ordered pairs listed in the table you constructed in part (b).
d. Describe the four characteristics of the association. Compute and interpret r as part of your analysis. If there is an association, draw an appropriate model in the scatterplot.
