# Determine The Least Square Equation

Question

The accompanying data were compiled by the superintendent of schools in a large metropolitan area. The table shows the average SAT verbal scores of high school seniors during the 5 years since the district implemented its “back-to-basics” program.

Year x                     1       2        3       4       5
Average Score y    430    432    430    426    426

Determine the equation of the least-squares line for these data.

a. y = –8/5x  + 433
b. y = –7/5x  + 428
c. y = 8/5x  + 428
d. y = 8/5x  + 433
e. y = –7/5x  + 433

Summary

The question belongs to Mathematics and it is about finding least squares equation for the data.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
