Essay

It is important to find characteristics of the production process that produce tortilla chips with an appealing texture. The following data on x = frying time (sec) and y = moisture content (%) are obtained: $$\begin{array} { c c c c c c c c c } \hline x & 5 & 10 & 15 & 20 & 25 & 30 & 45 & 60 \\\hline x & 16.3 & 11.4 & 8.1 & 4.5 & 3.4 & 2.9 & 1.9 & 1.3 \\\hline\end{array}$$
a. Construct a scatter plot of y versus x and comment.
b. Construct a scatter plot of the (In(x), In(y)) pairs and comment.
c. What probabilistic relationship between x and y is suggested by the linear pattern in the plot of part (b)?
d. Predict the value of moisture content when frying time is 20 in a way that conveys information about reliability and precision.
