194/2
So there is 97 people in each group
Subtract 9 so you have -2. Kx=-2 divide both sides by k. You have -2 over k

dependent variable = reaction time in milliseconds
Step-by-step explanation:
The linear regression statistical test is best used for research experiment where there is a single dependent and one independent variable whjre both variables are numeric. In the given options above, the city of residence, gender, college major and political affiliation are all possible categorical variables and age, salary, miles driven and reaction time are all numerical variables.

Answer:
67.5
Step-by-step explanation:
- When you calculate the 10% of AED75, it is equal to AED7.5
- Then you subtract AED7.5 from AED75 which is AED67.5
the answer is x is greater then -7
to find this add 4 to each side
then divide by -2.
since you divided both sides by a negative the symbol flips and you get x is greater then -7
