If the given v is greater than vg, we are in the gas region, use the superheat tables to find the given volume at the given temperature or pressure. If the given v is less than vf, we are in the compressed liquid region. If a compressed liquid table is not available we can find T for a given P using the saturation table for temperature.

Notice that for the slope (after the word “ACT”) under t value we have a t-value of 3.040. Now you can look up the critical value for the t distribution as described above for any given significance level. However, the two-sided P-value is already given to you under Pr(>|t|), which in this case is given to be “0.00292,” a small value.

a. Perform a t test using the p-value approach and determine whether or not Y and X are related. Let ( = 0.05. b. Using the p-value approach, perform an F test and determine whether or not X and Y are related. c. Compute the coefficient of determination and fully interpret its meaning. Be very specific. 5.

Summary: To find the p-value for the hypothesis test for the difference in means, look in the column labeled “Sig. (2-tailed)” in the “t-test for Equality of Means” section, and in the second row (labeled “Equal variances not assumed”).

This is used to generate critical values in the output and isn’t all that important as you will also be getting p-values with your output. The output looks like this. The mean, variance and number of observations are given for each group. The t-Stat is given. The p-values and …

The p-value is 0.056 so we do not reject the null hypothesis. The p-value is 0.112 so we do not reject the null hypothesis. The p-value is 0.888 so we do not reject the null hypothesis. The p-value is 0.944 so we do not reject the null hypothesis. The test for difference in proportions between two populations uses. the z-distribution. the f ...

Example 3: Find the P-value and decide whether to reject or not to reject Ho. Example 4: Find the P-value and decide whether to reject or not to reject Ho.

Therefore, P( t = tstat) = p-value. The excel function to find the p-value is =tdist(tstat, degs of freedom,2). Reject the null hypothesis. if the sample’s p-value is less than the chosen significance level “alpha” (.
