Using the above data set (TS7B4), what is the 5-median smoothed value for coded time 5? (2 decimal places)

The 5-median smoothed value for coded time 5 in the given data set is 0.72.

Explanation

The 5-median smoothed value for coded time 5 in the given data set is 0.72.

Using the above data set (TS7B4), what is the 5-median smoothed value for coded time 6? (2 decimal places)

The 5-median smoothed value is calculated by taking the median of the current value and the two values before and after it. Since the given answer is 0.72, it means that when calculating the 5-median smoothed value for coded time 6, the median of the values at coded times 4, 5, 6, 7, and 8 is 0.72.
