- the central limit theorem informs the numerator of the z- score for the sample means equation. true or false?arrow_forwardA local DMV (location of your choice) wanted to assess the number of mistakes that were made by its operators (aka clerks). One hundred samples were gathered from each of 20 operators (note: n = 100 for calculation of σp but you will need 100 * 20 to calculate p-bar). The results are shown in the table below. The DMV wants to set control limits to include 95% of the random variation. Operator # Number of errors Fraction defective Operator # Number of errors Fraction defective 1 6 11 6 2 5 12 1 3 0 13 8 4 1 14 7 5 4 15 5 6 2 16 4 7 5 17 11 8 3 18 3 9 3 19 0 10 2 20 4 Calculate p-bar and σp.
