Multiple Choice
The reading speeds (in tens of words per minute) and typing speeds (in words per minute) of nine randomly selected secretaries were recorded.
Dependent variable is: Reading speed
R-squared = 97.9521%
S = 2.094847 with 9 - 2 = 7 degrees of freedom
A) Reading speed = -40.738 + 2.260433 × Typing speed;We estimate that the reading speeds for these secretaries increase about 2.260433 words per minute for each 10 word per minute increase in their typing speed.
B) Typing speed = -40.738 × Reading speed + 2.260433;We estimate that the typing speeds for these secretaries increase about 2.260433 words per minute for each 10 word per minute increase in their reading speed.
C) Reading speed = -40.738 + 2.260433 × Typing speed;We estimate that the reading speeds for these secretaries increase about 22.60433 words per minute for each 1 word per minute increase in their typing speed.
D) Typing speed = -40.738 + 2.260433 × Reading speed;We estimate that the typing speeds for these secretaries decrease about 40.738 words per minute for each 10 word per minute increase in their reading speed.
E) Typing speed = -40.738 × Reading speed + 2.260433;We estimate that the typing speeds for these secretaries decrease about 40.738 words per minute for each 10 word per minute increase in their reading speed.
