a) The mean of the sample is 62.6 with a standard deviation of 6.4 b) Eighteen of the thirty temperatures fall within one standard deviation of the mean. This accounts for 60% of the temperature values. If the distribution of temperatures were perfectly normal, we would expect there to be roughly 68% of the values to fall within one standard deviation. c) Twenty-six of the thirty temperature values fall within two standard deviations of the mean. This accounts for 86.6% of the temperature values. If the distribution were perfectly normal, we would anticipate roughly 94% of the values to fall within this area. d) The distribution of the maximum temperature values of my town is not normal. While the percentage of temperatures that fall within one or two standard deviations of the mean is almost comparable to the ideal values of a normal distribution, the distribution generated by the temperature values is positively skewed. Further, not enough of the values fall within the ideal areas, limiting the
