Can you please let me know if I answered these word questions correctly. My book isn't exactly to the point. i understand if you can't. Thank you
You complete a hypothesis test using o=.05 and based on the evidence from the sample, your decision is to reject the null hypothesis. which of the following is true?
* you have made a type 1 error
* you might have made a type 1 error but the probability is less than 5% (this is the one i had chosen)
* you have made a type II error
* you have made the correct decision
you complete a hypothesis test using o= .05 and based on the evidence from the sample your decisions to fail to reject the null hypothesis. if the treatment actually does have an effect, which of the following is true?
* you have made a type II error ( this is the one i had chosen?)
* you might have made a type I error, but the probability is only 5% at most
* you have made a type I error
* you have made the correct decision
what is the relationship between the alpha level, the size of the critical region and the risk of type I error?
* as the alpha level increases the size of the critical region decreases, and the risk of a type I error decreases
* as the alpha level increases, the size of the critical region increases and the risk of a type 1 error decreases (this is the one i had chosen?)
* as the alpha level increases the size of the critical region decreases and the risk of a type 1 error increases
* as the alpha level increases the size of the critical region increases and the risk of a type I error increases.
by selecting a larger alpha level reseacher is
* better able to detect a treatment effect
* attempting to make it easier to reject Ho
* all of these choices are the result of selecting a lager alpha level (this is the one i had chosen)
* increasing the risk of a type I error
