Rewrite the equation so that the x term is on the left:

9 - 3x = -18

Move the number to the right and change the sign:

-3x = -18 - 9

-3x = -27

Change the sign of both terms:

3x = 27

Move the 3 to the right and change the sign:

x = 27 ÷ 3

x = 9 is your answer.

In a hypothesis test, what should we conclude if the data would be very unusual if the original assumption about our parameter w
Triss [41]

We conclude  the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.

  • A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
  • The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
  • If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.
