MATH399 Statistics Week 4 Lab Name: _Fifi Hartono______________________ Statistical Concepts: Probability Binomial Probability Distribution Calculating Binomial Probabilities Open a new Excel worksheet. 1. Open spreadsheet 2. In cell A1 type “success” as the label 3. Under that in column A, type 0 through 10 (these will be in rows 2 through 12) 4. In cell B1, type “one fourth” 5. In cell B2, type “=BINOM.DIST(A2,10,0.25,FALSE)” [NOTE: if you have Excel 2007, then the formula is BINOMDIST without the period] 6. Then copy and paste this formula in cells B3 through B12 7. In cell C1, type “one half” 8. In cell C2, type “=BINOM.DIST(A2,10,0.5,FALSE)” 9. Copy and paste this formula in cells C3 through C12 10. 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 D12 Plotting the Binomial Probabilities 1. Create plots for the three binomial distributions above. You can create the scatter plots 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 connecting lines.
