Vitamin D, whether ingested as a dietary supplement or produced naturally when sunlight falls upon the skin, is essential for strong, healthy bones. The bone disease rickets was largely eliminated during the 1950s, but now there is concern that a generation of children more likely to watch TV or play computer games than spend time outdoors is at increased risk. A healthcare provider took a sample of 285 randomly selected children and found 20% of them were deficient in vitamin...

A recent study conducted by the Crimes against Children Research Center has found that bullies tend to be victims of crime more often than non-bullies. Suppose the average number of victimizations for all children who are bullies is 3.0 with a standard deviation of 1.4. You take a sample of 49 children who have been identified as bullies by their peers and ask them to report the number of times they have been victimized. You calculate the mean number of...
