Ethan is conducting an experiment to determine whether a new medication is effective in reducing sneezing. he finds 1,500 volunteers with sneezing issues and divides them into 2 groups. the control group does not receive any medication; the treatment group receives the medication. the patients in the treatment group show reduced signs of sneezing. what can ethan conclude from this experiment?

Ethan can conclude that the new medication is effective in reducing sneezing

Explanation:
Now, Ethan wants to test a certain hypothesis that claims that the new medication is effective in decreasing sneezing.
The test can either:
1- show that patients sneezed less which supports his claims and thus, his hypothesis is verified
2- show that no the medication had no effect on patients which would contradict his hypothesis and reject it

We are given that those who took the treatment sneezed less. This means that the medication had an effect in reducing the sneezing as Ethan claimed from the beginning.

Therefore, he can conclude that his hypothesis is verified and the medication lessens sneezing

Hope this helps :)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
