Derive one Tail and Two Tail numbers for c = 0.88 or alpha = 0.12.

What is c?

z sub C

To derive one-tail and two-tail numbers for a given significance level (alpha), we need to use a statistical table for the desired test statistic distribution.

In this case, let's assume we are looking for the critical values of the t-distribution.

To find the one-tail and two-tail critical values, we need to know the degrees of freedom (df) associated with the t-distribution. This value depends on the sample size and the specific statistical test being conducted. If you have the degrees of freedom, you can directly find the critical values in the t-distribution table.

Once we have the degrees of freedom, we can go ahead and determine the critical values for alpha = 0.12.

For the one-tail test:
1. Locate the row in the t-distribution table corresponding to the degrees of freedom.
2. Find the column that corresponds to the desired alpha level (0.12).
3. The value you are looking for is the critical value (t-critical) for the one-tail test.

For the two-tail test:
1. Divide the desired alpha level (0.12) by 2, as two-tail tests distribute the alpha level across both tails.
2. Locate the row in the t-distribution table corresponding to the degrees of freedom.
3. Find the column that corresponds to the alpha level divided by 2.
4. The value you are looking for is the critical value (t-critical) for the two-tail test.

Please note that the specific values for c = 0.88 or alpha = 0.12 are not sufficient to determine the degrees of freedom or to look up the critical values. You will need to provide additional information regarding the degrees of freedom to find the critical values.
