The mean height of a certain kind of plant is 171 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 171. state the null hypothesis and the alternative hypothesis that we would use for this test.

Null Hypothesis:

Alternative Hypothesis:

Step-by-step explanation:

It is given that the mean height of a certain kind of plant is 171 centimeters.

Null Hypothesis: A hypotheses of no statistical significant difference is known as null hypothesis. The null hypotheses for this test is

Alternative Hypothesis: If a hypothesis is used in hypothesis testing that is contrary to the null hypothesis is known as alternative hypotheses. The alternative hypotheses for this test is

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
