Document Summary

Take a point estimate and then taking the point estimate into a standardized value. Keep your probabilbility value and take a point estimate into a standized value (for alternative value) Values rather than t scores. (it makes more sense) Example: suppose that you want to test the hypothesis that the proportion of the public who favors some public policy is not equal to 50%. You draw a sample of 1200 canadians and find that 53. 2% are in favor. Please test this hypothesis using the alternative approach. Our p value is less than our alpha value. We use our line of best fit to estimate the type of relationship. Generally, we use the line that minimized the sume of the square of the residuals. Minimize the distance from the points to the line of best fit. We try to estimate the size of slope coefficient.
