Consider the following five-point summary for a variable that was obtained using 200 observations. Minimun 26 01 46 Median 58 03 70 Maximum 90 a-1. Interpret Q1 Eighty percent of the observations are less than 46, 20% of the observations are greater than 45. Seventy-five percent of the observations are less than 46, 25% of the observations are greater than 46. Twenty percent of the observations are less than 46, 80% of the observations are greater than 46. Twenty-five percent of the observations are less than 46, 75% of the observations are greater than 46. a-2. Interpret 03. Eighty percent of the observations are less than 70.20% of the observations are greater than 70. Seventy-five percent of the observations are less than 70. 25% of the observations are greater than 70. Twenty percent of the observations are less than 70,80% of the observations are greater than 70. Twenty-five percent of the observations are less than 70, 75% of the observations are greater than 70. b-1. Calculate the interquartile range, Interquartile range b-2. Determine whether any outliers exist. No outliers exist. At least one outlier exists on the left side of the distribution At least one outlier exists on the right side of the distribution. Outliers exist on both the left and right sides of the distribution b-1. Calculate the interquartile range. Interquartile range b-2. Determine whether any outliers exist. No outliers exist. At least one outlier exists on the left side of the distribution. At least one outlier exists on the right side of the distribution Outliers exist on both the left and right sides of the distribution c. Is the distribution relatively symmetric? If not, comment on its skewness. The distribution is symmetric. The distribution is positively skewed. The distribution is negatively skewed. Symmetry or skewness cannot be determined with the available information
