Assignment:
Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r from Table A-6 using ?? =0 .05. Determine whether there is sufficient evidence to support a claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-3 exercises.)
Casino Size and Revenue Listed below are sizes (in thousands of square feet) and revenue (in millions of dollars) from casinos in Atlantic City (based on data from the New York Times). Is there sufficient evidence to conclude that there is a linear correlation between size and revenue of casinos?
