ONE-SAMPLE T-TEST 11 critical t-value: 2 201 p-value: p ? 0 03 Since the calculated t-value has an absolute value that is greater than the critical t-value we will reject the null hypothesis Thus a significant difference should be declared Also the p-value of 0 03 which is less than 0 05 also shows that
The t-table is good only for speci c values of so is not useful for calculating exact p-values The best we can do is bracket the p-value between two values of in the table Instead we can use the t-calculator on the same page in the Excel spreadsheet which gives us a p-value of 0 0081: Convert t to t df (one tail) (two tail)
