You are given the following summary statistics from a regression analysis:
ŷ = 200 + 150x
SSE = 25.25
SSX = Sum of squares X = (x -x) 2 = 99.645
n = 18
x = 52.0
a. Determine the point estimate for y if xp = 48 is used.
b. Provide a 95% confidence interval estimate for the average y, given xp = 48. Interpret this interval.
c. Provide a 95% prediction interval estimate for the average y, given xp = 48. Interpret this interval.
d. Discuss the difference between the estimates provided in parts b and c.
Step by step method for regression analysis is discussed here. Regression coefficients, coefficient of determination, scatter diagram and significance of regression model are explained in the solution.
