Solution to Example 4. The question is related to the average (mean) length of the tool and the sample size n = 200 n = 200 is large enough, we may therefore use the central limit theorem. Let X¯ X ¯ be the random variable representing the average (mean) of the sample. According to the central limit theorem, the distribution of X¯ X ¯ is ...A is the correct answer. Remember, in order to calculate the median, you must first order the values in the sample from lowest to highest.
