Question 12 (1 point) Listen ? Assume that there are on average 4 shark attacks per year in some region. How do I calculate the probability of observing 3 attacks or more in this region? 1 - ppois(g = 2, lambda = 4) ppois(q = 2, lambda = 4) 1 - pbinom(q = 2, lambda = 4) Question 10 (1 point) Listen ? Assume that there are on average 4 shark attacks per year in a certain region. How do I calculate the probability of observing 8 attacks in a year in this region? qpois(x = 8, lambda = 4) dpois(x = 4, lambda = 8) dpois(x = 8, lambda = 4) Question 9 (1 point) Saved Listen ? My simulation in R has produced the following output: [1] 0 0 1 1 0 0 0 4 0 1 Which of the following codes did I run? rbinom(8,4,.02) rbinom(10,3,2) rbinom(10,4,.2) Question 11 (1 point) Listen Assume that there are on average 4 shark attacks per year in a certain region. How do I calculate the probability of observing at most 3 attacks in this region? rpois(q = 3, lambda = 4) ppois(q = 3, lambda = 4) qpois(q = 3, lambda = 4)
