following questions. a. What are the mean and standard devation of this distribution? Round your answers to two decimal ploces, if necessary. b. You have to be more careful in interpreting @RISK probabilities with a discrete distribution such as this binomal. For example, if you move the left shider to 11 , you find probability of 0.139 to the left of it, But is this the probability of "less than 11 " or "less than or equal to 117 One way to check is to use Excel's BINomDist function. Use function to interpret the 0.139 value from eRISK. C. Using part b to guide you, use QRISK to find the probablity that a random number from this distributbon will be greater than 17 , Check your answer by using the BINOMDIST function appropriately in Excel. Round your answer to three decimal places, if necessary. Please provide steps and answers
