Answer:
I think the an 8..good luck
You need to figure out how many ways you can roll a sum of 9.
3 and 6, 4 and 5, 5 and 4, and 6 and 3. That's 4/36, or a 1/9 chance.
Alex has a 1/6 chance. Therefore, Alex is more likely to win.
Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
