The article Microwave Observations of DailyAntarctic SeaIce Edge Expansion and ContributionRates (IEEE Geosci. and Remote Sensing Letters,2006: 5458) states that The distribution of the dailysea-ice advance/retreat from each sensor is similar andis approximately double exponential. The proposeddouble exponential distribution has density functionf(x) 5 .5le2l|x| for 2` , x , `. The standard deviationis given as 40.9 km.a. What is the value of the parameter l?b. What is the probability that the extent of daily seaicechange is within 1 standard deviation of the meanvalue?
