A researcher proposes a Poisson distribution for X. Suppose that 1 = The Poisson probability mass function is: P(X - ) = al for x = 0,1,2,... Use the pmf to calculate probabilities. Verify these values in R using dpois(x,lambda). Compute the following probabilities: (Round your answers to three decimal places.) (a) P(X = 7) ( b ) P (X = 7 ) = (C) P(X - 7) (d) P(X - 7) = (e) P(2EX= 6) =
