Q. Baldwin has the following data:\newline5,17,t,125, 17, t, 12\newlineIf the range is 1212, which number could tt be?\newlineChoices:\newline(A)(A)1717\newline(B)(B)44
  1. Calculate Range Equation: Calculate the range of the data set. The range is the difference between the maximum and minimum values in the set. Since the range is given as 1212, we set up the equation: maxmin=12\text{max} - \text{min} = 12.
  2. Identify Maximum and Minimum: Identify the current maximum and minimum values without tt. Current values are 55, 1717, and 1212. Without tt, the minimum is 55 and the maximum is 1717.
  3. Substitute Known Values: Substitute the known max and min into the range equation: 175=1217 - 5 = 12. This equation is incorrect because 17517 - 5 equals 1212, which is not true; it equals 1212.
