For this case we have the following info given:
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
