Suppose we wish to test the hypotheses h0: μ = 10 versus ha: μ < 10, where μ represents the mean age of children not in high school who are members of a large gymnastics club in a metropolitan area. assume age follows a normal distribution with σ = 2. a random sample of 16 ages is drawn from the population, and we find the sample mean of these observations to be = 8.76. what is the value of the p-value?

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?
