Question 6. You are a teacher at a gifted school, and you feel that the newest class of students is even brighter than usual. The mean IQ at your school is 127, and the mean IQ of this new class is 134. In total, there are 32 students in this new class. Also, the standard deviation of the school's IQ is 8. Use the eight steps to test whether this new class of students is significantly more intelligent than the school's student body overall (take a picture of your hand-written notes and insert it into this document).

Question
The least squares regression equation for the association between Quality of Marriage (y) and Quality of Parent-Child Relationship (x) is as follows: . A) What is the value for i) the intercept and ii) the slope? Slope: Intercept: B) Based on this equation, what is the predicted Quality of Parent-Child Relationship for someone whose Quality of Marriage is 3? C) Now let's say in our data we have a person whose Quality of Marriage is 3 and his Quality of Parent-Child Relationship is 1. What is the residual in prediction? Question 6.
