Test the claim that there is correlation between (Consumer Price Index) CPI and Cost of Pizza with ? = 0.05. CPI 30.2 48.3 112.3 162.2 191.9 197.8 Cost of Pizza 0.15 0.35 1.00 1.25 1.75 2.00 The null and alternative hypotheses here are: (There is no linear correlation) (There is linear correlation) Next, find: p-value: (Correlation coefficient) r: Do you reject the null hypothesis or fail to reject the null hypothesis, circle one? Why did you reject the null hypothesis or fail to reject the null hypothesis? Does the data support the claim that there is correlation between CPI and pizza?
