Transcribed Image Text:(d) Predict the value of moisture content when frying time is 20, in a way that conveys information about reliability and precision. (Calculate a 95% PI. Round your answers to two decimal places.)
%,
(e) Analyze the residuals from fitting the simple linear regression model to the transformed data and comment. (Select all that apply.)
O The patterns in the residual plot and the normal probability plot are marginally acceptable.
O There are four positive standardized residuals.
O The patterns in the residuals plot and the normal probability plot are unacceptable.
O Looking at the residual versus fits, one standardized residual is a bit large.
O Looking at the residual versus fits, no standardized residuals look large.
O There are only two positive standardized residuals, but two others are essentially 0.
