Consider the following five-point summary for a variable that was obtained using 200 observations. a-1. Interpret Q1. Eighty percent of the observations ate less than 72,20% of the observations are greater than 72. Seventy-five percent of the observations are less than 72,25% of the observations are greater than 72 . Twenty percent of the observations are less than 72,80% of the observations are greater than 72 . Twenty-five percent of the observations are less than 72,75% of the observations are greater than 72 . a-2. Interpret 03 . Eighty percent of the observations are less than 96,20% of the observations are greater than 96 Seventy-five percent of the observations are less than 96,25% of the observations are greater than 96. Twenty percent of the observations are less than 96,80% of the observations are greater than 96 Twenty-five percent of the observations are less than 96,75% of the observations are greater than 96. b-1. Colculate the interquartile range b-1. Calculate the interquartile range. b-2. Determine whether any outliers exist. No outliers exist. At least one cutlier 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 telatively 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 avaliable information
