When using a t-test, how do we determine if we reject the null hypothesis?
What will be an ideal response?
In order to reject a null hypothesis the calculated t-value must be larger than a critical t-value, from the t-table. We choose a critical t-value by selecting a one- or two-tailed test, calculating the degrees of freedom, and selecting a probability level (usually 0.05 or 0.01). If the absolute value of the observed test statistic is greater than or equal to the critical value, reject the null hypothesis; if the observed t is smaller than the critical value, do not reject it.
