It Is Important to Find Characteristics of the Production Process

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.
