The null hypothesis in ANOVA one-way classification, the study of the variances due to k different sources, is:

For the price -quantity chart

If the difference between the rank of the 4 observations are 2.5, 0.5, -1.5, -1.5, then Spearman's rank correlation coefficient equals to:

If each observation in a data set for number of employees in different divisions is doubled then the coefficient of quartile deviation:

If Arithmetic mean and coefficient of variation of x are 10 and 40 respectively, then the variance of y = 10 – 2x is:

In one way ANOVA, σ² is estimated by:

For making frequency distribution, the number of classes used depends upon:

The second quartile for the following data 38, 39, 40, 52, 59, 67, 73, 77, 149, 248 is:

If the odds in favour of any random event A are 5 : 6, then the odds against the event are:

If the occurrence of events follows Poisson Process with mean rate λ, then inter-occurrence time of events will follow:
