Question

Which of the following statements likely would include information to produce null and alternative hypotheses statements for a potential study?

A. Green plants exhibit enough light

B. Green plants exhibit enough light for photosynthesis

C. Green plants do not exhibit a high rate of growth when planted close to light.

D. Green plants do exhibit high rates of growth.

Please explain any option you choose.

Answer 1

Here option C can be consider for hypothesis.

Null Hypothesis says that no statistically significance between the two variables

Alternative hypothesis says that there is statistically significance relation between two variables

So Null hypothesis : Green plants do not exhibit a high rate of growth when planted close to light

Alternative hypothesis : Green plants do exhibit a high rate of growth when planted close to light

Note :- Null hypothesis always be opposite of what we expect or study.

so here our question of interest is, if we plant a tree closer to a light will it grow faster...?

so here the posibilities are whether plant will grow faster OR it may not grow faster.

If we are interested to know that, planting a tree closer to a light will it grow faster...?

then Null hypothesis says if we plant a tree closer to light it will not grow faster..

this is the opposite statement to our question.(it will always try to disprove your statement)
