I need help!
It is claimed that a certain 6-sided die is biased so that it is more likely to show a six than if it was fair.
In order to test this claim at the 10% significance level, the die is thrown 10 times and the number of sixes is noted.
(i) Given that the die shows a six on 3 of the 10 throws, carry out the test.
On another occasion the same test is carried out again.
(ii) Find the probability of a Type I error.
I got part (i) right (0.225), but I can't understand how I'm supposed to attempt part two. The answer to (ii) is 0.0697.
