Document Summary
For all statistical tests, make sure that you clearly state your hypotheses. Some questions have a box for the final answer. Please put the final answer in this box, and show all work in the other space provided, including the back of the page if necessary. By taking this test and putting your name above, you are declaring that your answers on this test are all your own work. What is the probability that a fish can survive the first 10 crossings? (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.
