For a middle school science project, Jalen measured the pH of 25 vinegar products. The summary statistics for the values of the pH are shown in the following computer output. Variable pH N Mean Median StDev Minimum Maximum Q1 Q3 25 2.50 2.49 0.26 2.11 2.93 Based on the 1.5 x IQR rule for outliers, which of the following statements is true? 2.23 2.78 (A) The minimum pH value of 2.11 is an outlier, and no other pH value could be identified as an outlier. (B) The maximum pH value of 2.93 is an outlier, and no other pH value could be identified as an outlier. The minimum pH value of 2.11 is an outlier, and there could be other pH values identified as outliers that (C) are below the first quartile, but no pH value above the third quartile could be identified as an outlier. The maximum pH value of 2.93 is an outlier, and there could be other pH values identified as outliers that (D) are above the third quartile, but no pH value below the first quartile could be identified as an outlier. (E) There are no pH values that could be identified as outliers.
