1) The following are the highest temperatures recorded in eight specific states, find the mean. (5 points) 112, 100, 127, 120, 134, 118, 105 and 110 2) Find the variance and standard deviation of the above data of the highest temperatures recorded in eight specific states. (12 points) (x-x) (x-x) Sum Variance Standard Deviation 3) Create a normal distribution graph based on the mean and standard deviation from problem (1) and problem(2); up to 3 standard deviations in both directions.
