Question

If the results of a study using the one-sample t test were summarized t(14) = 3.218, p < .01, then you would know that the probability of tobs if H0 is true is and that the difference between X and μ is. 
A)less than or equal to .01; nonsignificant 
B)less than or equal to.01; statistically significant 
C)greater than .01; nonsignificant 
D)greater than .01; statistically significant

The result t(14) = 3.218 indicates that the t-value calculated from the sample is 3.218 standard errors away from the mean. The p-value < .01 indicates that the probability of getting a t-value as large as 3.218 (or larger) if the null hypothesis is true is less than .01. This means that the results are statistically significant at the .01 level of significance, providing evidence against the null hypothesis. Therefore, the answer is B, less than or equal to .01 and statistically significant.
