If the number n is rather big, then binominal distribution practically equal to the normal distribution with the expected value np and dispersion npq. This calculator calculates the probability density function, cumulative distribution function, mean, and variance for given p and n. ...
The calculator below calculates the mean and variance of the negative binomial distribution and plots the probability density function and cumulative distribution function for given parameters: the probability of successp, number of successesk, and the number of trials to plot on chartn. ...
The probability of 10 Patientswill be- P(x=10) = 0.1074 Therefore, P(x=9)+P(x=10) = 0.268 + 0.1074 = 0.3758 Thus, the probability of 9 or more patients being treated with the drug is 0.375809638. Binomial Distribution Calculator ...
Variance is a measure of dispersion that is used to check the spread of numbers in a given set of observations with respect to the mean. Understand variance using solved examples.
The adjusted degrees of freedom are: (2)(1/2) = 1 for the numerator and (90)(1/2 = 45 for the denominator The probability value is obtained using the F probability calculator with the new degrees of freedom parameters. The probability of an F of 228.06 of larger with 1 and 45 ...
