Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

WebbThe P-value for conducting the left-tailed test H 0: μ = 3 versus H A: μ < 3 is the probability that we would observe a test statistic less than t* = -2.5 if the population mean μ really … Webb6 aug. 2024 · the probability of getting head in 1 toss is P ( H 0 ) = 1/2 = 0.5 . so if our coin is not biassed towards the head then the probability of getting 5 heads in 5 tosses, P ( X = 5 H 0 ) = 1/ 32 = 0.03 because if our coin is not biassed towards the head then there is only 1 possibility out of 32 possibilities to getting all heads.
Webb10 sep. 2024 · Ex: Suppose you are testing the following hypothesis at a significance level (α) of 5% and you got the p-value as 3%, and your sample statistic is x̄ = 25 H₀: μ = 20 H₁: μ > 20 The interpretation of the p-value as follows: We saw above that α is also known as committing Type-I error. WebbStep 5: Find the test statistic using this formula: z = (140 – 100) / (15/√30) = 14.60. Step 6: If Step 5 is less than -1.96 or greater than 1.96 (Step 3), reject the null hypothesis. In this …
