to be purple, 20% of the flowers are white and the rest are in
other colors. A farmer decided to check whether the distribution of
flower colors in glass-enclosed greenhouses matches the
distribution of colors of all the flowers growing in the country.
To do this, he took a random sample of 100 flowers grown in
glass-enclosed greenhouses and found that 50 of them were purple,
25 of them white and the rest of them in other colors.
