Sickle-cell disease is a hereditary medical condition affecting red blood cells. Some forms are benign, but other forms cause health problems leading to reduced life expectancy. Sickle-cell appears to protect against malaria, which may explain why it comes from tropical sub-Saharan Africa where malaria is endemic. A group of African children were

In a study of pulse rates of men, a simple random sample of 143 men results in a standard deviation of 11.7 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the
