For this example question, X≥3, so type “3” into the box.

Step 5: Click the “Input Constant” radio button and then type your X-value into the box. Step 2: Click the “Cumulative Probability” radio button. Step 6: Click “OK.” The probability of a cumulative event: X ≥3, n=10, p(0.15) Step 5: Click the “Input Constant” radio button and then type your X-value into the box. 1, and df (degrees of freedom) is 100, what is the p-value (b) Suppose the test statistic is. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. In the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. for this sample question, the probability is 0.15. Press OK and Minitab returns the following output, in which I've highlighted the p-value. Step 4: Type the probability “p” into the Event probability box. for this sample question, the number of trials is 10. Step 3: Type the number of trials “n” into the Number of Trials box. Step 2: Click the “Probability” radio button. Step 1: Click “Calc,” mouse over “Probability Distributions” and then click “Binomial.” The probability of a single event: X=3, n=10, p(0.15) The test statistic, 2 34.01, lies very far in the tail of a chi-square distribution with 2 degrees of freedom, so the p-value is very close to zero.

The value “X” for a known probability (i.e.The probability of a cumulative event (i.e.The probability of a single event (i.e.

How you find binomial probabilities in Minitab depends on which type of event you have: a trial with only two possible outcomes, like tossing a coin). For what By going to the Help menu, selecting StatGuide, Graphs, and. A Binomial Distribution) shows either (S)uccess or (F)ailure.īinomial probability is a way of calculating the probability of an event happening in a binomial trial (i.e. For example, the normal plot produced by these commands includes a P value.
