A consortium of 50 clothing producers sells its stock through one or more merchants

exclusive (ie each merchant is associated with one and only one producer).We shoot a

sample of 12 producers for whom we observe two variables X and Y where X represents the

number of merchant (s) associated with a producer and Y represents sales (in tens of thousands

dollars) in the past month.Here is the sample data

Estimate the standard deviation of the estimator of the total number of producers with exactly two associated merchants
