Answer #1

A normal distribution is a symmatrical distribution about it's mean .Therefore, no skewness and it is mesokurtic.

d) A normal random variable is a continuous random variable taking any value on real axis.

a) Since it is a continuous random variable , the probability of each individual value or probability at a certain point will be zero.

c) Since It is a symmetric distribution . Mean = median = mode

b) As A norma variable can take any value between -infinity to +infinity. It assumes uncountable number of points .

clearly option (b) is incorrect.

Which of the following is false? The normal distribution is defined by two parameters, the mean and the standard deviation. In a normal distribution, the probability that the random variable X takes a particular value is zero. For a continuous random variable the probability associated with any values of the random variable is found by calculating the area under the relevant normal curve. For a normal distribution, approximately two thirds of the observations will fall within two standard deviations either...
