Web1 Answer. Sorted by: 1. p_value = 2 * stats.norm.cdf (lift, loc = 0, scale = scale_val ) This is the key for your question: The p-value is the probability that the null hypothesis is true. If the null hypothesis is true: Your model does not find any differences between groups. If false: Your model finds differences between groups. WebThis is a ' two-tailed ' test, because the alternative hypothesis claims that the proportion is different (larger or smaller) than in the null hypothesis. If the data supports the alternative hypothesis, we reject the null hypothesis and accept the alternative hypothesis. 3. Deciding the Significance Level. The significance level ( α) is the ...

Web9 de fev. de 2024 · Since norm.pdf returns a PDF value, we can use this function to plot the normal distribution function. We graph a PDF of the normal distribution using scipy, numpy and matplotlib. We use the domain of −4< 𝑥 <4, the range of 0< 𝑓 ( 𝑥 )<0.45, the default values 𝜇 =0 and 𝜎 =1. plot (x-values,y-values) produces the graph.
