failing to reject the null hypothesis when it is false.

The sampling statistic is = 16.65, however from the table, the critical values are () = 27.4884 and () = 6.26
Conclusion: There is no reason to reject that = 2.02.

In this example, .151 is not less than or equal to .05, so we fail to reject H0.

You can use the F statistic when deciding to support or reject the . In your F test results, you’ll have both an F value and an F critical value.


failing to reject the null hypothesis when it is true.

NOTE: Excel can actually find the value of the CHI-SQUARE. To find this value first select an empty cell on the spread sheet then in the formula bar type "=CHIINV(D12,2)." D12 designates the p-Value found previously and 2 is the degrees of freedom (number of rows minus one). The CHI-SQUARE value in this case is 12.07121. If we refer to the CHI-SQUARE table we will see that the cut off is 4.60517 since 12.07121>4.60517 we reject the null. The following screen shot shows you how to the CHI-SQUARE value.

In this setting, the p-value is based on the hull hypothesis and has nothing to do with an alternative hypothesis and therefore with the rejection region.

This was also a tradeoff between"type I error" and "type II error"; that we do not want to accept the wrong null hypothesis, but we do not want to fail to reject the false null hypothesis, either.

Paired Sample t Test | Real Statistics Using Excel

Power and Alpha (): Thus, the probability of not rejecting a true null has the same relationship to Type I errors as the probability of correctly rejecting an untrue null does to Type II error.

Measurement Systems Analysis (MSA)/Gage R&R

The task is to decide whether to accept a null hypothesis: H = = or to reject the null hypothesis in favor of the alternative hypothesis: H: is significantly different from The testing framework consists of computing a the t-statistics: Where is the estimated mean and S is the estimated variance based on n random observations.

What is the acceptable range of skewness and kurtosis …

To justify or reject such a claim, you could look at the variation within each group (one group being women's salaries and the other group being men's salaries) and compare that to the variation between the means of randomly selected samples of each population.

Therefore, there is not sufficient evidence to reject the null hypothesis that the two correlation coefficients are equalClearly, this test can be modified and applied for test of hypothesis regarding population correlation based on observed r obtained from a random sample of size n:provided | r | 1, and | | 1, and n is greater than 3.
