Type a "0" to create a null hypothesis symbol or "1" to create an alternative hypothesis symbol. Alternatively, type an "o" or "a" to represent the null and alternative hypotheses, respectively, although these symbols are not as frequently used. Advertisement Step 5 Press the subscri...
State the null hypothesisandalternate hypothesis. Choose analpha level. Find thecritical value of zin az table. Calculate the z test statistic (see below). Compare thetest statisticto the critical z value and decide if you shouldsupport or reject the null hypothesis. ...
Let us compare the scores of students from Class B and Class C to check if Class C students have higher scores than Class B students. First, we need to assume the null and alternate hypotheses for this test. Null Hypothesis (H0): There is no difference in the scores of both divisions....
If youreallywant to run Bartlett’s test by hand, follow these steps [2]. Bartlett’s Test for Equality of Variances by Hand The null hypothesis for the test states that the variances are equal for all samples, which in statistical notation is expressed as: H0: σ12= σ22= … = σ...
Suppose you conduct a test and your p-value is equal to 0.02. What can you conclude? What do we conclude if the p-value is larger than the significance level (\alpha)? How do you find the p-value to prove or disprove a null hypothesis? Answer the following questions with Explanation....
Degree of freedom (DF): It is the number of observations in a data set that are free to vary while estimating statistical parameters. t-value: It is the result that is obtained out of a t-test calculation. The value determines whether to accept or reject the null hypothesis. When the ...

The following null and alternate hypotheses are used in a one-way ANOVA. H0: All group means are equal. HA: Not all group means are equal. We reject the null hypothesis and come to the conclusion that not all of the group means are equal if the overall p-value of the ANOVA is less...
p is lesser in magnitude than 0.05 we need to reject the null hypothesis. There is a statistically significant difference between the sample mean of the two different samples. Paired T-Test The paired sample t-test is also called a dependent sample t-test. Let’s take an example from a ...
You could take your calculated chi-square value and compare it to a critical value from a chi-square table. If the chi-square value is more than the critical value, then there is a significant difference. You could also use a p-value. First state the null hypothesis and the alternate hy...
