In cell D1 type “three fourths”11. In cell D2, type “=BINOM.DIST(A2,10,0.75,FALSE)”12. Copy and paste this formula in cells D3 through D12Plotting the Binomial Probabilities1.Create plots for the three binomial distributions above.You can create the scatterplots in Excel by selecting the data you want plotted, clicking on INSERT, CHARTS,SCATTER, then selecting the first chart shown which is dots with no connectinglines.Do this two more times and for graph 2 set Y equal to ‘one half’ and X to‘success’, and for graph 3 set Y equal to ‘three fourths’ and X to ‘success’.Pastethose three scatter plots in the grey area below.(9 points)

View the AnswerCalculating Descriptive StatisticsYou will use the same class survey results that were entered into the worksheet for theWeek 2 iLab Assignment for question 2.2.Calculate descriptive statistics for the variable (Coin) where each of the thirty-fivestudents flipped a coin 10 times. Round your answers to three decimal places andtype the mean and the standard deviation in the grey area below.(5 points)Mean:Standard deviation:Short Answer Writing Assignment – Both the calculated binomial probabilities and thedescriptive statistics from the class database will be used to answer the followingquestions.Round all numeric answers to three decimal places.3.List the probability value for each possibility in the binomial experiment calculated atthe beginning of this lab, which was calculated with the probability of a success being½. (Complete sentence not necessary; round your answers to three decimal places) (8points)P(x=0)P(x=6)P(x=1)P(x=7)P(x=2)P(x=8)P(x=3)P(x=9)P(x=4)P(x=10)P(x=5)4.Give the probability for the following based on the calculations in question 3 above,with the probability of a success being ½. (Complete sentence not necessary; roundyour answers to three decimal places)(8 points)P(x≥1)P(x<0)P(x>1)P(x≤4)P(4<x ≤7)P(x<4 or x≥7)
