Answer #1

a p-value represents:

the probability, given the null hypothesis is true, that the results could have been obtained purely on the basis of chance alone

So C is the right answer

Justification-p value is probability null hypothesis is true obtain a value more extreme than test statistic..so C is the only choice matching with this

Note-if there is any understanding problem regarding this please feel free to ask via comment box..thank you

    Which of the following is not an appropriate interpretation of the p-value you computed in the exercise above? in this case p value=0.001812 The p-value above is the probability the null hypothesis is true. If the treatments had exactly no effect on the patient's outcome, it would be very unlikely to see sample results like we did (or something more extreme) due to sampling variability alone. We have very strong evidence that the type of treatment a patient receives for...

    6.) P-values: First, and most important, what is a p-value? A p-value is the probability of getting the sample results IF the null hypothesis is true. This is the definition of a p-value. VERY IMPORTANT: A p-value is NOT the probability of the null hypothesis being true. If you remember only one statistical thing from this exam, please remember this idea regarding p-values. Also, look into the following regarding p-values: a.) How are they calculated? b.) How are they used...
