Chapter 13, Problem 15(choose chapter or problem)
No tortilla chip aficionado likes soggy chips, so it is importantto find characteristics of the production process thatproduce chips with an appealing texture. The following dataon x 5 frying time (sec) and y 5 moisture content (%)appeared in the article Thermal and Physical Propertiesof Tortilla Chips as a Function of Frying Time (J. ofFood Processing and Preservation, 1995: 175189).x 5 10 15 20 25 30 45 60y 16.3 9.7 8.1 4.2 3.4 2.9 1.9 1.3a. Construct a scatterplot of y versus x and comment.b. Construct a scatterplot of the (ln(x), ln(y)) pairs andcomment.c. What probabilistic relationship between x and y issuggested by the linear pattern in the plot of part (b)?d. Predict the value of moisture content when fryingtime is 20, in a way that conveys information aboutreliability and precision.e. Analyze the residuals from fitting the simple linearregression model to the transformed data and comment.
