Exhibit 16-4.The following data shows the cooling temperatures of a freshly brewed cup of coffee after it is poured from the brewing pot into a serving cup.The brewing pot temperature is approximately 180º F;see http://mathbits.com/mathbits/tisection/statistics2/exponential.htm For the assumed exponential model ln(Temp)= β_{0} + β_{1}Time + ε,the following Excel regression partial output is available. Refer to Exhibit 16-4.What is the sample correlation coefficient between ln(Temp)and Time?
A)-0.9701
B)0.9701
C)-0.9849
D)0.9849
