Lego sells individual minifigures in opaque packages, so you don’t know which one you are buying. in the current series there are 16 different minifigures available. i already own several minifigures and really only want to get 2 specific ones. if my son and i go shopping (and don’t want to spend half an hour feeling up each and every package), what is the minimum number of packages we should buy to have at least a 60% chance of getting at least 1 of the 2 figures we want? (assume that each store has a large number of packages which contain a random and even distribution of all the 16 possible minifigures.)

The wall street journal reported that walmart stores inc. is planning to lay off 2,300 employees at its sam's club warehouse unit. approximately half of the layoffs will be hourly employees (the wall street journal, january 25-26, 2014). suppose the following data represent the percentage of hourly employees laid off for 15 sam's club stores. 55 56 44 43 44 56 60 62 57 45 36 38 50 69 65 (a) compute the mean and median percentage of hourly employees being laid off at these stores. (b) compute the first and third quartiles. (c) compute the range and interquartile range. (d) compute the variance and standard deviation. (e) do the data contain any outliers? (f) based on the sample data, does it appear that walmart is meeting its goal for reducing the number of hourly employees?
