I need help finding the median

Question

Suppose that a category of world class runners are known to run a marathon (26 miles) in an average of 143 minutes with a standard deviation of 14 minutes. Consider 49 of the races.

Let x̅ = the average of the 49 races.

I need help finding the median of the average running times

Answer 1

The distribution of sample means is approximately normal if the sample size is greater than 30 per the central limit theorem. For a normal distribution the mean=median=mode.
