Percentages are included by default in the frequency tables. If you want to include them on the chart, double click on the chart, and you will open the "Chart Editor" window; then right click on the chart and select the "show data labels" option. This will open the "Properties" window, where you can select "Percentage" and click "Apply"
Just to be clear. It appears that there are 2 ways to reject null hypothesis or fail (accept) to reject it. You can compare the t statistic (for the formula) to the table value of t critical as determined by degrees of freedom and confidence level. OR you can find the p value for the table value of t critical and see if it is less or greater than alpha to reject or fail (accept) to reject null hypothesis?
