The sum and the sum of squares of length x (in cm) and weight y (in g) of 50 plant products are given below:

Which is more variable, the length or weight?

RS Aggarwal - Mathematics

If x_{1}, x_{2}, ……, x_{n} are n values of a variable X and y_{1}, y_{2}, ……., y_{n} are n values of variable Y such that y_{i} = ax_{i} + b, i = 1,2, ……, n, then write Var(Y) in terms of Var(X).

The mean and variance of the heights and weights of the students of a class are given below:

Which shows more variability, heights or weights?

If the sum of the squares of deviations for 10 observations taken from their mean is 2.5, then write the value of standard deviation.

RD Sharma - MathematicsThe mean and standard deviation of 18 observations are found to be 7 and 4 respectively. On rechecking it was found that an observation 12 was misread as 21. Calculate the correct mean and standard deviation.
