Parker is testing 2 different types of ant killer in his yard. He purchases Brand A and Brand B from the home improvement store. He applies Brand A in the front yard on Monday and Brand B in the backyard on Saturday. He then compares the ant hills on Sunday and determines that Brand A is more effective than Brand B. Why is his conclusion not valid?

He purchased 2 different types of ant killer. He did not say how many ant hills he had at the beginning of the test. He did not wait as long between each treatment of ant killer. He applied 1 treatment to the front yard and 1 treatment to the backyard.

i feel like it's C cause it wouldn't make sense to wait longer for one of the brands and not for the other

the only way to find out is to test multiple times not just one time there is no sufficient data to make such a conclusion
