Your data set has missing values. Further examination tells you that they are spread along 1.5 standard deviation from the median with distribution mean = 0 & variance = 5. How much data would remain unaffected( in % )?

I have no idea about this problem how to solve this and whats the relation between standard variation and variance while computing a median in the data cleaning process in data visualization. and can't find any resource also. So, I asked here to know whats the fundamental behind this process. thanks
