Now that the mean and standard deviation have been found, the STANDARDIZE function can be used to find the z-score for the sixth patient. Refer to your Excel spreadsheet. The STANDARDIZE function has the format STANDARDIZE(value to find the z-score of, sample mean of data, sample standard deviation of data). The amount of time the sixth patient had to wait in an office with a tracking system is located in cell C7 Correct: Your answer is correct. . The sample mean and standard deviation of the data was computed in cells C12 and C13, respectively. Thus in cell E7, the formula to use to find the z-score for the sixth patient is =STANDARDIZE( C7, $C$12, $C$13 Correct: Your answer is correct. ). Enter this value below, rounding to two decimal places.
