Question

the mean height of a certain kind of plant is 125 centimeters. suppose we want to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 125. state the null hypothesis $h_0$ and the alternative hypothesis $h_1$ that we would use for this test.
$h_0$:
$h_1$:

Explanation:

Step1: Define null hypothesis

The null hypothesis $H_0$ is a statement of no - effect or no - difference. Here, it is that the mean height of the plants after treatment is the same as the original mean height. So, $H_0:\mu = 125$.

Step2: Define alternative hypothesis

The alternative hypothesis $H_1$ is what we are trying to find evidence for. Since we want to test if the mean height differs from 125, it is a two - tailed test. So, $H_1:\mu
eq125$.

Answer:

$H_0:\mu = 125$
$H_1:\mu
eq125$
