Webb3 feb. 2024 · If the null hypothesis was true what is the probability of observing a test statistic at least as extreme as ours. The smaller the p-value the stronger the evidence to reject the H₀. Step 4:... Webb9 juni 2024 · The number of times a value occurs in a sample is determined by its probability of occurrence. Probability is a number between 0 and 1 that says how likely something is to occur: 0 means it’s impossible. 1 means it’s certain. The higher the probability of a value, the higher its frequency in a sample.
