WebbReturns the probability that values in a range are between two limits. If upper_limit is not supplied, returns the probability that values in x_range are equal to lower_limit. Syntax. … WebbWe can see that the probability of a Type I error is α = K ( 100) = 0.05, that is, the probability of rejecting the null hypothesis when the null hypothesis is true is 0.05. We can see the power of a test K ( μ), as well as the probability of a Type II error β ( μ), for each possible value of μ.
