1. The following data represent the continuous random variable which is the precipitation totals for the month of September in 21 different towns in Alaska. Use 6 classes and construct a frequency histogram of this data. Explain the resulting probability distribution characteristic ( symmetric , skewed left, skewed right ). Use this histogram as the probability distribution function for this random variable to answer the question : During the month of September in Alaska what is the probability that a town would receive precipitation in excess of 3 inches ? 2.7 1.72 1.39 6.88 2.59 2.04 2.43 9.28 1.06 3.29 1.57 4.23 0.95 8.37 0.6 4.41 6.73 1.92 2.74 18.65 2.28
