Using the Bonferroni post hoc test, the overall probability of making a Type I error can be kept at a p level of 0.05 by:
A) dividing 0.05 by the number of comparisons you plan to make and using the result as the p level for each comparison.
B) dividing 0.05 by 2 and using the result as the p level for each comparison.
C) determining the amount of difference you should have between each of your means based on a p level of 0.01.
D) finding the honestly significant difference.

The Bonferroni correction is a method to adjust the p-values of statistical tests when multiple comparisons are made, in order to control the overall Type I error rate. To use the Bonferroni post hoc test, the alpha level (typically 0.05) is divided by the number of comparisons being made. This ensures that the probability of a Type I error across all the comparisons is no more than 0.05. Therefore, choice A is the correct answer.
