Question

5. In this question, you are asked to learn about the pbinom command in R. If X ~Bin (n.p), then calculating the cdf at r (same as caing Pr (X S) can be done in R using the pbinom command: pbinom(x, n, p) (a) (2 points) Write down the R code to calculate Pr (X 8) if XBin (25,0.4). What is your result from R? result from R? result from R? (b) (2 points) Write down the R code to calculate Pr (X <8) if XBin (25,0.4). What is your (c) (2 points) Write down the R code to calculate Pr (X2 8) if XBin (10,0.5). What is your

Answer 1

I am attaching the R code for part (a) , (b) & (c)

Ans Pr (X<=8) = 0.2735315

Ans Pr (X<8) = 0.0546875
