1] Suppose we have the following measurements for the weights (in kg] of femaie polar bears (data looser based on a study by Regebr et a1. (2%)}: 211.9 149.9 105.3 113.5 [24.2 :1} Calculate the sample mean. b} Calculate the sample median. 2] Let's stick with our polar bears. Suppose we add another female who weighs 338.8 kg :1} Calculate the sample mean ofthis new sample. b} Calculate the sample median of this new sample. e} Which statistic {mean or median} do you think better represents this new sample of IS polar bears? My? d} Blotting question: can you think of any reason why a female polar bear would weigh 333.3 kg when most females weigh much less? {Hintz it's a femaJel]. 3) Make up a sample of'size n = T for which the average is #13 {note the [-} sign]. Not all 7 numbers should be identical
