If two distributions have equal means, then

Two distributions have the same mean Rs. 7500 and standard deviations Rs. 9 and Rs. 12 respectively. If C.V. of the first distribution is 24% , find the C.V. of the second distribution.

Two distributions A and B have the same mean. If their coefficients of variation are 6 and 2 respectively and sigma _(A),sigma_(B) are their standard deviations,then

In a symmetric distribution, the mean and the mode are

Consider the following frequency distribution What is the mean of the distribution?
