I was wondering how you would answer this question?

33. (2 marks) Assume you have conducted a study similar to Lab 8, (Crossman's Confusion Function). You remember the lab; it's the one with the lines of different lengths. A group of subjects was tested on 4 conditions. The equation is: DRT = a + b (log2 X1 - log2 X2) bits The common line length is 93 mm, the other 4 lines were 92 mm, 91 mm, 89 mm, 87 mm. Data and an analysis is presented on the next page. What score would you predict for a subject who was tested using a condition with the common line and a line of 90 mm? A. 360.9 B. 362.1 365.0 D. 404.5 E. 443.9 . 765.6
