Question

Section-I State whether the following statements are True or False. (6 marks, 1 Mark each) 1. The hypothesis that an analyst is trying to prove is called the alternative hypothesis. 2. One-way ANOVA is used when analyzing the difference between more than two population means. 3. If r = 0.9, then r 2 = 0.81, which means that 19% of the total variation in y remains unexplained. 4. The chi-square goodness-of-fit test cannot be used to test for normality. 5. If x and y have a strong positive linear correlation, r is close to 0. 6. A test of independence CHI-SQUARE tests the null hypothesis that in a contingency table, the row and column variables are independent
