Document Summary
Statistics 2 exam 2: study guide: compute the intercept of the regression line if xbar= 66, ybar = 254, sy= 39, sx. Y intercept: y-bar (slope * x-bar: a study of nutrition in developing countries collected data from the egyptian village of nahya. Here are the mean weights (in kilograms) for 170 infants in. Nahya who were weighed each month during the first year of life. Find the 95% confidence interval for the slope. n=12. The regression equation is weight = 4. 88 + 0. 267 age. The standard error is given in the regression output. (se coefficient: . 0393) The critical value is a factor used to compute the margin of error. With simple linear regression, to compute a confidence interval for the slope, Statistics 2 exam 2: study guide the critical value is a t score with degrees of freedom equal to n - 2. To find the critical value, we take these steps.
