Step 1 :First, let's identify the outliers in each dataset.
Step 2 :For dataset a: \(\begin{array}{lllllll} 5 & 7 & 7 & 8 & 12 & 33 \end{array}\), the outlier seems to be 33.
Step 3 :For dataset c: \(\begin{array}{llllll} -58 & -60 & -59 & -4 & -64 \end{array}\), the outlier seems to be -4.
Step 4 :Now, let's calculate the mean and median for each dataset.
Step 5 :Dataset a: Mean = \(\frac{5+7+7+8+12+33}{6} = 12.0\), Median = \(\frac{7+8}{2} = 7.5\)
Step 6 :Dataset c: Mean = \(\frac{-58+-60+-59+-4+-64}{5} = -49.0\), Median = -59
Step 7 :\(\boxed{\text{Dataset a: Outlier: 33, Mean: 12.0, Median: 7.5}}\)
Step 8 :\(\boxed{\text{Dataset c: Outlier: -4, Mean: -49.0, Median: -59}}\)
