MAT1080 Midterm Part A Form 27 NAME: Due before Tuesday, October 27, at 5:00PM . Scan to a PDF and submit on D2L. Some work must be shown. If the work is mostly getting numbers from StatCrunch or using a calculator, you must at least first show the equation that would be used if doing it by hand. Even if the answer seems obvious, some justification must be provided. If ever doubtful how much work must be shown, ask. Find the mean of the data summarized in the given frequency distribution. 1) The heights of a group of professional basketball players are summarized in the frequency distribution below. Find the mean height. Round to one decimal place. If using StatCrunch, first show the equation you would use for doing it by hand. Height (in.) 70 - 71 Frequency 1 72 - 73 8 74 - 75 13 76 - 77 8 78 - 79 15 80 - 81 6 82 - 83 (for work, just show equation) (SHOW WORK) FINAL ANSWER: H = (value) (units) Solve the problem. Round results to the nearest hundredth. 2) The mean of a set of data is -2.91 and its standard deviation is 3.88 Calculate the z score for an x value of 2.80 (SHOW WORK) FINAL ANSWER: Z =
