If a random sample of 400 crickets in the wild is chosen, approximately how many would be expected to live at least 44.4 days? [ans2] 3. Approximately what percentage of crickets in the wild live between 53.8 and 82.0 days? [ans3] 4. Approximately what percentage of crickets in the wild live less than 44.4 days? [ans4]
