a. Construct a scatter plot. What does the scatterplot suggest about a linear correlation between time and distance?
b. Find the value of the linear correlation coefficient and determine whether there is sufficient evidence to support the claim of a linear correlation between weight and price of gold.
Use a significance level of 0.05.
c. Letting y represent the time and let x represent the distance, find the regression equation.
d. Based on the given sample data, what is the best predicted price for a piece of gold that weighs 1.5 ounces?
