Which of the following is NOT a property of a normal distribution?

a) Unimodal

b) Area under the curve equals 1

c) Symmetric

d) 95% of the data will lie within one standard deviation of the mean

Solution

a) The normal distribution is unimodal because there is only one peak

b) ANy distribution, the area under the curve equals 1.

c)In normal distribution mean , mode and medain is equal So, this is symmetric

d) In normal distribution 95% of the data will lie within two standard deviation of the mean

and 68% of the data will lie within one standard deviation of the mean. So

d is not aproperty of a normal distribution.
