Question

Consider the below data for ALL PARTS of this question: 4 2 5 7 8 12 23 24 12 17 3 What is the sample MEAN? Note: Enter XX AT LEAST ONE DIGIT BEFORE THE DECIMAL. ONE AFTER and round up AFTER all calculations. Thus, 7 is entered as 7.0, 3.562 is entered as 3.6, 0.3750 is entered as 0.4: 17.351 is entered as 17.4 Consider the below data for ALL PARTS of this question: 4 2 5 7 8 12 23 24 12 17 3 What is the sample MEDIAN? Note: Enter X.X AT LEAST ONE DIGIT BEFORE THE DECIMAL ONE AFTER and round up AFTER all calculations. Thus, 7 is entered as 7.0: 3.562 is entered as 3.6 0.3750 is entered as 0.4; 17.351 is entered as 17.4 Consider the below data for ALL PARTS of this question: 4 2 5 7 8 12 23 24 12 17 3 What is the sample MODE? Note: Enter XX AT LEAST ONE DIGIT BEFORE THE DECIMAL ONE AFTER and round up AFTER all calculations. Thus, 7 is entered as 7.0:3.562 is entered as 3.6 0.3750 is entered as 0.4; 17.351 is entered as 17.4 Consider the below data for ALL PARTS of this question: 4 2 5 7 8 12 23 24 12 17 3 What is the sample STANDARD DEVIATION? Note: Enter XX AT LEAST ONE DIGIT BEFORE THE DECIMAL ONE AFTER and round up AFTER all calculations. Thus. 7 is entered as 7.0: 3.562 is entered as 3.63 0.3750 is entered as 0.4: 17.351 is entered as 17.4
