Now that the mean and standard deviation have been found, the STANDARDIZE function can be used to find the z-score for the tenth patient. Refer to your Excel spreadsheet. The STANDARDIZE function has the format STANDARDIZE(data value to find the z-score of, sample mean of data, sample standard deviation of data). The amount of time the tenth patient had to wait in an office without a tracking system is located in cell B11 Correct: Your answer is correct. . The sample mean and standard deviation of the data was computed in cells B12 and B13, respectively. Thus in cell D11, the formula to use to find the z-score for the tenth patient is =STANDARDIZE( B11, $B$12, $B$13 Correct: Your answer is correct. ). Enter this value below, rounding to two decimal places
