Document Summary

There is a relationship. critical f score = f. inv. rt(alpha), dfr, dfe) --> assume . 05 unless given something else. P value / signifiance f = f. dist. rt(f, dfr, dfe) # of observations = total +1 standard error = square root of the variance variance = mse r^2 = multiple coefficient of determination. Anova f stat when h1 is > greater than that means right tail. Surveyed sample amount of 40 students from a population of 200. If both are given, test ratioif ratio is more than 5%, use finite correction factor. Since n/n or 40/200 = . 2% > . 05 apply finite correction factor. 92% confidence interval = 8 percent for both tails, 4% in each tail. Margin of error = cv * standard error. With proportions, critical value is always z z score table and look for 4% inside of table = -1. 75 = Standard error = square root of (p*q/lower case n) for proportion.
