Answer:
41.67% probability that a student has a dog given that they have a cat
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: having a cat.
Event B: having a dog.
12 of 27 students have a cat:
This means that 
5 students who have a cat and a dog.
This means that 
What is the probability that a student has a dog given that they have a cat?

41.67% probability that a student has a dog given that they have a cat

Answer:
c. The score on the achievement test of both groups.
Step-by-step explanation:
A school psychologist recruits 600 second-grade students and randomly divides them into two groups.
Group 1 is taught by means of the new method, while Group 2 is taught via traditional methods.
We have to find the response variable. A response variable is the outcome variable or dependent variable in the experiment.
Here this is - The scores on the achievement tests of both group 1 and group 2.
The answer is: [B]: " 3.99 * 10⁻⁶ " .

Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —
___________________________________________________
→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;
______________________________________________
is the smallest value ; and as such, the correct answer.
