Inadequate exposure to outdoor lighting conditions may increase the risk of myopia in children. A study was designed to estimate the rates of myopia among young children (6-7 years old) in Australia. A random sample of 124 young children in Australia was selected, and the researchers found that 7 of them had myopia.

Our test statistic is more extreme than our critical value of 1.645. We reject the null hypothesis and conclude that more than 4% of Australian young children has myopia. B.
