Work:

(a) For normal distribution curve mean, median and mode coincide. Also every distribution

is divided into two equal parts by its median, i.e. symmetric about median. Since for a

normal distribution curve mean is same as median, the distribution is symmetric about its

mean.

(b) If all the observations in a data set are identical, then its arithmetic mean is also has the

same value of the observations. Therefore, it can be observed that all the...
