A professor in a probability class gives a student a coin, and instructs the student to determine whether the coin is a fair coin (that is, whether it has the same likelihood of landing on heads as landing on tails). The student flips the coin 500 times and records the outcome each time. They then find the proportion of heads and tails obtained in the 500 flips and create a histogram from the data. The set of observed outcomes (heads and tails) along with the proportions obtained by the student is

The blue whale is the largest animal living on the earth. the average blue whale measures 100 feet long (30 meters) and weighs 300,000 pounds (136,000 kilograms). a whale’s head is 1⁄3 of the length of its body. a new baby whale is 1⁄4 the length of a grown whale. the average man is 1⁄17 the length of a blue whale, and 1⁄1,818 its weight. a human baby measures 1⁄4 of the length of an adult. calculate the following information: how long is a whale’s head? how long is a new baby whale? how tall is the average man? how much does the average man weigh? how tall is the average human baby?
