Sаy yоu’re investigаting hоw mаny snakes are оn each plane in the sky at any given time. With a sampling distribution mean of 11 and a standard error of the mean of 2.1, what are our odds (expressed as a proportion) of drawing a subsample of 55 planes that has a mean of exactly 8 snakes or FEWER? Calculate a z-score, round the z-score to the nearest hundredth, SKETCH the distribution to help, and use the Standard Normal Table from our book to help find the answer. HINT: Pay attention to whether or not your z-score is negative and if you need to consider the left-hand side of the distribution or the right-hand side of the distribution.
