There is evidence of a small effect on memory by her experimental treatment.

Respuesta :

Answer: Option B is correct.

Explanation:

The p - value that is for a given model, the probability that, when the null hypothesis is correct/true, the summary will be equal to, or to a certain extent more than , the observed result but in this case it is quite high which leaves us with a little evidence of any effect. Hence,  In this case if there is a treatment effect, the sample size taken in consideration was too small to detect it.
