Jenelle can conclude from this experiment that the medication was effective in reducing sneezing
Step-by-step explanation:
As Janellle wants to test the medicine based on experimental grouping
The experiment can:
Either show that there was no effect on volunteers' sneezing even after taking medicine hence the medicine was of no use
Or the people who took the medicine sneezed less after the experiment hence the medicine was effective in reducing sneezing.
As it is given that the people of treatment group showed reduced signs of sneezing, it can be concluded that the medicine helped in reducing the sneezing among the treatment group ..
