25 mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. she purchases two different types of lamps from a local store. mina applies brand a to one area of the yard and brand b to another area of the yard, both of which receive full sunlight. she waters the area with brand b daily; she waters the area with brand a every other day. at the end of the study, mina concludes brand b is more effective in growing strawberry bushes. is mina's conclusion valid? explain why or why not.

No, her conclusion is not valid.

Step-by-step explanation:

In order to determine whether 1 lamp is more effective than the other, all other variables have to be the same.

Because Brand B was watered daily and Brand A was watered every other day, there is no way of knowing if the results were conclusive because of the heat lamps or the different watering patterns.

Hope this helps:)

Step-by-step explanation:

she needs to keep the watering consistent for both areas to keep the constants the same
