Answer 1

The statistical software output for this problem is:

Simple linear regression results: Dependent Variable: Deaths Independent Variable: Cases Deaths = -0.96232198 -0.6857761 Cases Sample size: 12 R (correlation coefficient) = 0.9624875 R-q-0.9263822 Estimate of error standard deviation: 1.3143685 Parameter estimates: Parameter Estimate Std. Err. Alternative DF T-Stat P-value Intercept -0.96232198 0.56057488 = 0 10 -1.7166698 0.1168 Slope 0.6857761 0.061133417 0 10 11 217696 <0.0001

From above output:

Linear correlation coefficient = 0.962
