Question

A. I got (.125, .036) Calculate a 95% confidence interval for the population slope, being sure to show all work. Round final endpoints to 3 decimal places. b.) The statement "researchers believe that the more money a student's parent's make, the higher that student's GPA will be," is equivalent to saying there is a positive, linear relationship between parents income and student's GPA for all current Kirksville High School students. Does your confidence interval support this statement? Explain your answer.

Explanation / Answer

Solution:

Great! You found confidence interval for slope which is (.125, .036)

First I will give a general interpretation for slope: If your slope(a1) is positive then we can say that y increases by1 units as x increases by a1 units. That means there is a positive linear relationship between x and y.

Suppose your x: Money a student's parent's make

y: Student's GPA

Confidence interval of slope is positive that means slope must be positive.

Hence we can say that confidence interval support your statement.
