Biotechnology Progress


An article in Biotechnology Progress (Vol. 17, 2001, pp. 366–368) reported an experiment to investigate and optimize nisin extraction in aqueous two-phase systems (ATPS). The nisin recovery was the dependent variable (y). The two regressor variables were concentration (%) of PEG 4000 (denoted as and concentration (%) of (denoted as x2).

 

(a) Fit a multiple linear regression model to these data.

(b) Estimate and the standard errors of the regression coefficients.

(c) Test for significance of β1 and β2.

(d) Use the model to predict the nisin recovery when x1 = 14.5 and x2 = 12.5. Construct a 95% PI.

(e) Compute the mean response of the nisin recovery when x1 = 14.5 and x2 = 12.5. Construct a 95% CI.

(f) Interpret parts (d) and (e) and comment on the comparison between the 95% PI and 95% CI.
