(i) grade point average in freshman year and in sophomore year

(ii) grade point average in freshman year and in senior year

(iii) length and weight of two-by-four boards Possible values for correlation coefficients are

-0.50 0.0 0.30 0.60 0.95 Match the correlations with the data sets; two will be left over. Explain your choices. P-698
