The probability of finding a value of t for variable X1 that is as large or larger than |2.133| when the null hypothesis is true is: A. between 5% and 10%. B. between 2% and 5%. C. between 1% and 2%.
In the table above, for 19 degrees of freedom, the value 2.133 would lie between a 2% chance (alpha of 0.02) or 2.539 and a 5% chance (alpha of 0.05) or 2.093.
