=+A.10 If the temperature in Florida falls below 32°F during certain periods of the year, there is a chance that the citrus crop will be damaged. Suppose that the probability is .1 that any given tree will show measurable damage when the temperature falls to 30°F. If the temperature does drop to 30°F, what is the mean number of trees showing damage in orchards of 2000 trees? What is the standard deviation of the number of trees that show damage?
