Answer:
0.67; The least-squares regression line, given by ŷ = 3.95 + 0.67x, is not a good fit for the data.
Step-by-step explanation:
Plot the data in a spreadsheet and insert a trendline. The line of best fit is y = 0.67x + 3.95. The r² value is 0.67.
The last option:The change in y-values is constant for evenly spaced x-values.
Remember that the change in y divided by the change in x is the slope of a line and it is constant.
