Plotting the Binomial Probabilities
1. Create plots for the three binomial distributions above. You can create the scatter
is
plots in Excel by selecting the data you want plotted, clicking on INSERT, CHARTS,
Th
SCATTER, then selecting the first chart shown which is dots with no connecting
lines. 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’. Paste
those three scatter plots in the grey area below. (12 points)
