If Mark chose a .01 significance level, it means he set his alpha level to be .01. Alpha level is the probability of rejecting the null hypothesis when it is actually true. So, if the probability of results occurring by chance is more than 1 out of 100 times, it means that the p-value is greater than .01, therefore we fail to reject the null hypothesis. Therefore, Mark should accept the null hypothesis.
