(10 points) The probability that it survives one cross is 1-pr[dies per cross] = 1 - 0. 1 = 0. 9. Each crossing is independent, so the probability of surviving ten times is 0. 910 = What is the relationship between the type i error rate and the significance level of a hypothesis test? (6 points) Type i error is rejecting a true null hypothesis.
