Question 3 For which of the following correlations would the data points be clustered most closely around the regression line?r= +0.45r= +0.79There is no relationship between the correlation and how close the points are to the regression line.r= -0.84r= 0.001 pointsQuestion 4A researcher was comparing several groups of female subjects to examine the effect on diet on mean waist circumference change following 12 weeks of dieting. The researcher obtained an F-ratio of 2.57 with df = 4, 67 from an independent-measures One Way ANOVA. Assuming there are no missing values, what is the total number of subjects N employed in the study?a.N = 71b.N = 67c.N = 64d.N = 721 pointsQuestion 5A researcher was comparing several groups of female subjects to examine the effect on diet on mean waist circumference change following 12 weeks of dieting. The researcher obtained an F-ratio of 2.57 with df = 4, 67 from an independent-measures One Way ANOVA. Assuming there are no missing values, what is the total number of treatment groups G being compared in the study?a.G = 4b.G = 6c.G = 5d.G = 671 pointsQuestion 6 A researcher was comparing several groups of female subjects to examine the effect on diet on mean waist circumference change following 12 weeks of dieting. The researcher obtained an F-ratio of 2.57 with df = 4, 67 from an independent-measures One Way ANOVA. What is the p-value for the F-test rounded to 3 decimal places? Please provide your answer to three decimal places (as X.XXX).2 pointsQuestion 7 A researcher was comparing several groups of female subjects to examine the effect on diet on mean waist circumference change following 12 weeks of dieting. The researcher obtained an F-ratio of 2.57 with df = 4, 67 from an independent-measures One Way ANOVA. Using the p-value obtained previously, which of the following statements (if any) is true?There is a statistically significant difference at the 5% level which can be intrerpreted as that at least one of the group means is differentThere is a statistically significant difference at the 5% level which can be interpreted as all the group means are the sameThere is not a statistically significant difference at the 5% level which can be interpreted as all the group means are the sameThere is not a statistically significant difference at the 5% level which can be interpreted as that at least one of the group means is different2 points
