Answer:
1. single sample design
2. matched pairs
3. two independent samples.
Step-by-step explanation:
the response variable is known as the dependent variable, it is the variable that the researcher is interested i finding. the response variable is the x variable that responds to changes in the independent variable.
1.
In this question the researcher has only one sample that is the specimen. that is the reference specimen that she obtained. Therefore it is a single sample design.
the response variable here is the measurement of concentration.
2. In this question we have two pairs, men and women. The researcher is interested in comparing attitudes as she interviews them. so response variable is attitude or behavior
3. this is a 2 independent sample design. The researcher is using two different methods to test and their average is being compared.
Answer:
the answer is 45 . so circle 4
Solution :
Transforming given equations :

From above equations we can see that equation 1) has largest percentage growth rate and the percent growth rate is 12% .
Hence, this is the required solution.
.484 is the ansewer since 4.4 *.11 is .484 hope this helps
Answer:
15 liters
Step-by-step explanation:
Given:
We need 5 liters of Yoda soda for 12 guest.
To find:
If we have 36 guest how many liters of Yoda soda we need.
Solution:
<u>By unitary method:</u>
For 12 guests, we need liters of Yoda soda = 5
For 1 guest, we need liters of Yoda soda = 
For 36 guests, we need liters of Yoda soda = 
Therefore, we need 15 liters of Yoda soda for 36 guests.
