a. In a left-tailed test, α=.05, the critical value of z is: -1.645 -1.96 2.33 -2.58 b. The ____________ is the same as the point-slope form equation of a line, that is used for prediction. trendline regression line frequency polygon none of these c. If two variables are significantly correlated, we can predict the value of the dependent variable if we know the value of the independent variable. The process is called _______ correlation analysis hypothesis testing regression analysis estimation
