A variable is normally distributed with mean 6 and standard deviation 2, determine the quartiles of the variable, obtain and interpret the 80th percentile, find the value that 65% of all possible values of the variable exceed, find the two values that divide the area under the corresponding normal curve into a middle area of 0.95 and two outside areas of 0.025
