i am confused? Recall the following summary statistics for our sample of white wine pH measurements.Z =X-Z =S= -1.24=3.0Wines with low pH taste tart and crisp whereas wines with higher pH are more susceptible to bacterial growth. A pH of about 3.0 to 3.4 is most desirable forwhite wines.Variable NameDetermine the relative standing for a pH of 3.0 and a pH of 3.4 by computing a z-score for each observation, using the rounded values above and rounding eachz-score to two decimals.z-score for pH of 3.0X - XSz-score for pH of 3.43.41.403.1883pH0.15103.1883♥N0.1510Mean Standard Deviation Median Minimum Value Maximum Value4,898 3.1883the mean.0.15103.18Taking the absolute value of each z-score gives the following interpretations for each pH.A pH of 3.0 is -1.24X standard deviations belowabove2.72♥3.82the mean whereas a pH of 3.4 is 1.40standard deviations
