Answer:

a) According to empirical rule, 95% of the observations lies within 2 standard deviations of the mean.

Therefore 95% is the correct answer here.

b) 96.44 can be written as: 98.07 - 3*0.43 that is 3 standard deviations less than the mean

Also, 99.36 = 98.07 + 3*0.43 that is 3 standard deviations above the mean.

According to the empirical rule, 99.7% of the observations lies within 3 standard deviation of the mean.
