1. Explain the table. X 15 N 16 2 17 2 18 N O the table is undefined O the measures will be 2 O the measures will be zero\f7. Get the coefficient of skewness. O 0 O 1 O 2 8. Refers to question number 6. What type of skewness it is? O positively skewed O not skewed negatively skewed 9. When the distribution is less spread out than normal, its kurtosis is greater than 3 and it is said to be O leptokurtic O platykurtic O Other:10, 7, 6, 4, and 3 (data for questions 4-7) 4. Find the variance for ungrouped data. O 7.6 7.5 O 7.4 5. Find the standard deviation. 2.76 2.75 O 2.74 6. Look for coefficient of variation. O 45.67 or 45.7 O 45.68 or 45.7 O 45.8233. Find the standard deviation for grouped data. See the table below. 13-17 5 15 13-22 5| 20 23-27 10 25 23-32 15 30 33-37 12 35 38-42 13 40 43-47 7 45
