Big Steel Company recorded an efficiency rating at each of its four manufacturing locations every day for a fourteen-day period (provided below). As a member of their evaluation team you are asked if the average efficiency is the same across all locations. Determine your hypotheses, run the appropriate test, and provide the appropriate conclusion to the director of your team.

We have the following expression:
 S = 6x ^ 2
 We must clear x from the equation.
 For this, we follow the following steps:
 Step 1)
 Pass 6 to divide:
 S / 6 = x ^ 2
 Step 2)
 Square root on both sides:
 +/- root (S / 6) = x
 Step 3)
 Multiply numerator and denominator by 6:
 x = + / - root (6S / 6 * 6)
 Step 4)
 Rewrite expression:
 x = + / - root (6S / 36)
 Step 5)
 Take root to denominator:
 x = + / - (root (6S)) / 6
 
 x = + / - (root (6S)) / 6
 (option 2)
