represent the sample size
represent the sample mean
represent the sample deviation
We can calculate the confidence interval for the mean with the following formula:
The confidence level is 0.90 then the significance level would be 
and the degrees of freedom are given by:
And the critical value for this case would be:
And replacing we got:
And for this case since the confidence interval contains the value 0 we don't have significant evidence that we have a net change or efectiveness in the levels

<h3>What is nominal and ordinal scale with example?</h3>
- Examples of data for a nominal scale include a person's gender, ethnicity, and hair color.
- On the other hand, an ordinal scale requires putting data in a certain order, or in relation to one another and "ranking" each parameter (variable).
<h3>What is the difference nominal and ordinal?</h3>
- Ordinal data has a preset or natural order, whereas nominal data is categorized without a natural order or rank.
- A number that can be measured, however, will always be present in numerical or quantitative data.
