Question
Based on an analysis of sample data, an article proposed the pdf f(x) = 0.35e-0.35(x − 1) when x ≥ 1 as a model for the distribution of X = time (sec) spent at the median line. (Round your answers to three decimal places.) (a) What is the probability that waiting time is at most 8 sec? More than 8 sec? at most 8 sec P(X ≤ 8) = 0.826 more than 8 sec P(X> 8) = 0.174 X (b) What is the probability that waiting time is between 4 and 7 sec? 0249
