Question 10 (3 marks). A random variable X has its probability density function f (x ) given by fx(z) = 2e -2(3+2) ifx > -2 otherwise The function has been implemented in R as follows: f = 2, 2*exp(-2* (x-2) ), 0) } Which of the following R calls would correctly calculate P(X > 2.9)? O integrate (f, lower=2, upper=Inf) O integrate (f, lower=-Inf, upper=-2) O integrate (f, lower=-2, upper=2.9) O integrate(f, lower=2.9, upper=Inf) O integrate (f, lower=2, upper=2.9) O integrate (f, lower=0, upper=2.9)
