Suppose a research paper states that the distribution of the daily sea-ice advance/retreat from each sensor is similar and is approximately double exponential. the proposed double exponential distribution has density function f(x) = 0.5λe−λ|x| for −[infinity] < x < [infinity]. the standard deviation is given as 39.8 km. (round your answers to four decimal places.) (a) what is the value of the parameter λ?
