1. Whenever your decision is to reject the null hypothesis, there is a risk of a Type I error. True False 2. A Type I error occurs when you conclude that a treatment effect exists, but the treatment has no effect. True False 3. The critical region consists of extreme sample values that are very unlikely to occur if the null hypothesis is true. True False 4. A non directional test is considered a 2-tailed test True False 5. If a mechanic looks at your car engine and says there is nothing wrong with it and your car breaks down when you leave the garage, what type of error did the mechanic make? Type IType II No error made 6. Let's use a shepherd and wolf example. Let's say that our null hypothesis is that there is \"no wolf present.\" Assuming a non directional hypothesis test, what would be the alternative hypothesis? A shepherd present A wolf present 7. Again our null hypothesis is that there is \"no wolf present.\" Let's assume there is no wolf present; however, the shepherd raises the alarm by screaming \"Wolf! Wolf!\" What type of error is this? Type IType II No error made 8. Again our null hypothesis is that there is \"no wolf present.\" Let's assume there is no wolf present and the shepherd does not raise an alarm. What type of error is this? Type IType II No error made 9. Again our null hypothesis is that there is \"no wolf present.\" Let's assume there is a wolf present; however, the shepherd does not raise an alarm. What type of error is this? Type IType II No error made 10. Again our null hypothesis is that there is \"no wolf present.\" Let's assume there is a wolf present and the shepherd raises the alarm by screaming \"Wolf! Wolf!\" What type of error is this? Type IType II No error made
