Looking at histogram below you can see the random variable X is symmetric with mean 0 and median 0. What can you work out using the fact that X= 2.96 is the 85.35 th percentile

Histogram of a variable X -5 -4 -3 -2 -1 0 1 2 3 4 5 O a. 11.65% are more than 2.96 so 17.65% are less than -2.96 and the middle 69.70% are between -2.96 and 2.96 O b. 17.65% are more than 2.96 so 11.65% are less than -2.96 and the middle 72.70% are between -2.96 and 2.96 O c. None of the other choices are correct O d. 14.65% are more than 2.96 so 14.65% are less than -2.96 and the middle 70.70% are between -2.96 and 2.96
