This proves that her experimental treatment has no effect on memory

Explanation:

In an experimental setup, if the P valvue is less than 0.05, then there is a significant effect in the stated hypothesis being tested for.

In the case of the researcher, for her toget a p value as 0.17 which is above the 0.05 shows that there her experimental treatment has no effect on human memory.
