Vinnic is trying to modify a die by rounding off some edges. He is trying to increase the probability of rolling a 5.
A) What is the probability of rolling a 5 with a fair die?
B) Vinnie wants to see, "Do I have statistically significant evidence that my altered die will roll a 5 more often than a fair die?" What should he use as as the null and alternative hypothesis for this test? He tests his die by rolling it 4100 times, and the die comes up five 738 times during these rolls.
