Altman and Bland report the survival times for patients with active hepatitis, half treated with prednisone and half receiving no treatment. The data that follow are adapted from their data for those treated with prednisone. The survival times are recorded to the nearest month: 8 87 93 127 147 133 148 157 162 165 11 52 97 139 109 120 57 142 144 65 a. Look at the data. Can you guess the approximate shape of the data distribution? b. Construct a relative frequency histogram for the data. What is the shape of the distribution? C. Are there any outliers in the set? If so, which survival times are unusually short? Altman and Bland report the survival times for patients with active hepatitis, half treated with prednisone and half receiving no treatment.
