Critical region calculator t test
WebStep 1: Subtract one from your sample size. This is your df, or degrees of freedom. For example, if the sample size is 8, then your df is 8 – 1 = 7. Step 2: Choose an alpha level. … WebJun 11, 2024 · We use X as test statistic. a. Calculate the critical area for alpha = 0.05 b. The measured X=10, calculate the P-value ans: [14.98, infinity) and p = 0.135 . I know that the critical area is the collection of values for which H0 is rejected in favor of H1. In the case of a normal distribution I know how to calculate the critical region.

Significance Level: … WebSTEP 2 - Assign probabilities to our null and alternative hypotheses. H 0: p = 0.35 H 1: p ≠ 0.35 As this is a two-tailed test, the probability of the alternative hypothesis is just different to 0.35. STEP 3 - Write out our binomial distribution. STEP 4 - Calculate probabilities using binomial distribution.
