In the table below, X1 is a random sample of 20 observations from an exponential population with parameter β = 1.44, so that the median, η = 1. X2 is the same data set plus a constant, 0.6, and random Gaussian noise with mean μ = 0 and standard deviation σ = 0.15.

(i) Consider the "postulate" that the median for both data sets is η0 = 1 (which, of course, is not true). Generate a table of signs, Dmi , of deviations from this postu- lated median.
(ii) For each data set, determine the test statistic, T +. What percentage of the observations in each data set has plus signs? Informally, what does this indicate about the possibility that the true median in each case is as postulated?
