The 'pizza connection' is the principle that the price of a slice of pizza is always about the same as the subway fare. Us the pizza and subway cost data in the table below to determine whether there is a linear correlation between these two items. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Based on these results, does it appear that the subway fare is always about the same as a slice of pizza? Use a significance level of α = 0.05. Click here for data on pizza costs and subway fares over the years. The linear correlation coefficient is r= 0.986. (Round to three decimal places as needed.) Determine the null and alternative hypotheses. ... Ho: p = H₁:p #0 (Type integers or decimals. Do not round.) Determine the test statistic. The test statistic is t= 16.73. (Round to two decimal places as needed.) Determine the P-value. 0 The P-value is (Round to three decimal places as needed.)
