A typing instructor builds a regression model to investigate what factors determine typing speed for students with two months of

instruction. Her regression equation looks like: Y' = 11 + 7x1 + 5x2 + 3x3 where: Y' = typing speed in words per minute; x1= hours of instruction per week; x2= hours of practice per week; x3 = hours of typing per week necessary for school or work; A new student is taking 2 hrs of typing instruction per week, will practice 5 hrs per week and must type 2.5 hours per week for work. If the standard error of the estimate is 2, within what range do we have a 95.45% probability that that student's typing speed will be in two months?
Select one:
a. 53.5 and 61.5 words per minute
b. 49.5 and 65.5 words per minute
c. 57.5 and 65.5 words per minute

BabaBlast [244]

The answer to the blank space is a contrast effect. A contrast effect is defined as a psychological bias where individuals are prone to evaluating that a stimulus is more positive because a similar stimulus was previously perceived as negative.

This is what is going on with Tom; despite having been presented information by Sam regarding how low taxes in general creates higher tax revenue, Tom still believes that taxing the rich would generate greater tax revenue to reduce the effect of recession.
