A random sample of 9 biology students produced the following data,

first test score, x 2nd test score, y
84 31
52 69
40 32
23 32
67 40
37 88
15 96
82 88
30 53

where x measures the 1st test score and y measures the second test score. What is the estimate of the y = a x + b regression intercept coefficient?

Solutions

Expert Solution

Regression analysis :Is the relationship between dependent variable and independent variable or predictor variable and outcome variable these are called regression coefficient

Regression Analysis Y=a+bX

Y=67.1429-0.1751X

a=67.1429 = intercept

b=-0.1751 = slope
