A simple random sample of pages from Merriam-Webster's Collegiate Dictionary, 11th ed. was obtained. The sample mean is 53.2 words, the standard deviation is 15.0 words. Using the formula for z scores from your formula sheet, please type out how you would place the given numbers into the formula for your calculations. State the z score rounded to two decimal places. Using the z score only, determine if 90 words is an unusually high (or significantly high) number of words found on a page. Once again, be sure to type out your calculations, and write your conclusion in complete sentences.
