Answer:

Chisquare statistic

Step-by-step explanation:

The most appropriate test to use here is the Chisquare test as it isemployed when testing the relationship between two variables. Both the T statistic and z statistics are the used for testing difference in means. However, in the analysis above, we are given two variables with each having its own levels. Hence, the Chisquare test is the most appropriate in this kind of situation a it measures if a difference exists between the two variables. It tests if they are related or independent of on one another

Solve for h<br> h - 3h - 8 = 14<br> H=?
sweet [91]

The initial step that must be taken before solving almost any problem is to understand what the problem is asking for us to do and what is provided to us to complete that goal.  Looking at the problem statement, we can see that we are being requested to solve for h and we are provided an expression to do so.  Let's begin solving the expression by combining like terms.

<u>Combine like terms</u>

  • h - 3h - 8 = 14
  • (h - 3h) - 8 = 14
  • (- 2h) - 8 = 14

Just a quick explanation on what combine like terms means, it basically just means to combine the coefficients of the numbers associated with the same variables.  Like in this example we can combine h and -3h because they have have the variable h associated with them.

<u>Add 8 to both sides</u>

  • (- 2h) - 8 = 14
  • (- 2h) - 8+ 8 = 14 + 8
  • - 2h= 22

<u>Divide both sides by -2</u>

  • - 2h= 22
  • \frac{- 2h}{-2}= \frac{22}{-2}
  • h= \frac{22}{-2}

<u>Simplify the expression</u>

  • h= - \frac{22/2}{2/2}
  • h= - \frac{11}{1}
  • h= - 11

Therefore, after completing the steps above we were able to determine that the value of h is equal to -11.
