17. What statistical technique is normally used for comparing two nominal variables. 18. What statistic is utilized to determine the p value of repeatability in the technique that compares two nominal variables? ( Z, t, chi-square, F ) distribution. (circle one). 19. If the area that a home is located in is trying to be related to the agency that sold the house, write the null and alternate hypothesis. Ho: Ha: 20. What does the notation fo stand for in the analysis of two nominal variables? What does the notation fe stand for? 21. If the slope of a regression line in "flat" (that is, slope of 0 ), then varying the x value (will, will not, sometimes will) change the value of y. Circle one. 22. When the coefficient of correlation is +1 , the graph of y vs x is (horizontal, slopes upward, slopes downward). Circle one 23.
