An experimenter suspects that a certain die is "loaded;" that is, the chances that the die lands on different faces are not all equal. Recall that dice are made with the sum of the numbers of spots on opposite sides equal to 7: 1 and 6 are opposite each other, 2 and 5 are opposite each other, and 3 and 4 are opposite each other.

The experimenter decides to test the null hypothesis that the die is fair against the alternative hypothesis that it is not fair, using the following test. The die will be rolled 40 times, independently. If the die lands with one spot showing 11 times or more, or 1 time or fewer, the null hypothesis will be rejected.

Under the null hypothesis, the distribution of the number of times the die lands showing one spot is binomial with parameters n=40, p=1/6

Under the null hypothesis, the expected number of times the die lands showing one spot is 6.667 and the standard error of the number of times the die lands showing one spot is 2.357. The significance level of this test is ___________?
