Q4 : 
= 0.00401x+0.88929
We know that the regression equation is given as below
= (Slope)x+(y-intercept)
For the given case, the slope is given as 0.00401 and y-intercept is given as 0.88929. Hence the regression equation is given as below
= 0.00401x+0.88929
Thus option c is the correct answer
Q6 :
400 : Not appropriate
As the scores of quantative section ranged from 480 to 700, an input of 400 is not appropriate for this model
500 : 2.89
A score of 500 is in the range of 480 to 700. The predicted GPA can be found by substituting x=500 in the regression equation
Predicted GPA = 0.00401*500+0.88929 = 2.89
600 : 3.30
A score of 500 is in the range of 480 to 700. The predicted GPA can be found by substituting x=500 in the regression equation
Predicted GPA = 0.00401*600+0.88929 = 3.30

GRE SCORES: The test scores for the verbal reasoning and the quantitative reasoning section of the Graduate Record Examination (GRE) are normally distributed. In a recent year, the mean test score was 150 and the standard deviation was 8.75. The test score of a student is selected at random. What is the probability that the student's test score is LESS THAN 162? Round your answer to 4 decimals.

A university made an analysis of the relationship between the Math SAT scores (range 200-800) and first-year GPAs(range 0 to 4.0) for students who complete the first year. The average SAT score is 531 and the SD is 76 and the average GPA is 2.75 and the SD is 0.65. Suppose the correlation coefficient is found to be 0.7. a) A student is chosen at random and has a SAT score of 678. Use regression to predict this student's GPA....
