Chapter 4, Problem 4.134(choose chapter or problem)
In the text of this section, we noted the relationship between the distribution function of a beta-distributed random variable and sums of binomial probabilities. Specifically, if Y has a beta distribution with positive integer values for and and 0 < y < 1, F(y) = " y 0 t1(1 t)1 B(, ) dt = n i= n i yi (1 y) ni , where n = + 1. a If Y has a beta distribution with = 4 and = 7, use the appropriate binomial tables to find P(Y .7) = F(.7). b If Y has a beta distribution with = 12 and = 14, use the appropriate binomial tables to find P(Y .6) = F(.6). c Applet Exercise Use the applet Beta Probabilities and Quantiles to find the probabilities in parts (a) and (b).
