1. What is a one tailed test? What are the conditions needed for a
one tailed test? - Answer: ✔✔Alternative hypothesis in the
form P<... or P>.... You know how the null hypothesis is wrong,
and what it is biased towards.
2. What is a two tailed test? What are the conditions needed for a
two tailed test? - Answer: ✔✔Alternative hypothesis in the
form P≠.... You don't know how the null hypothesis is wrong
3. What is the critical region? - Answer: ✔✔The region of the
probability distribution in which if your test statistic falls, you
would reject your null hypothesis
4. What is a hypothesis in the the binomial distribution? - Answer:
✔✔A statement made about the value of the probability p in
the binomial distribution X-B(n,p),
5. What is a test statistic? - Answer: ✔✔The result of the
experiment which can be used to reject or support the null
hypothesis
6. What would the test statistic of seeing if a coin was biased
towards heads by doing 8 tosses be? - Answer: ✔✔The test
statistic would be the number of heads in 8 tosses
