Answer:
hhhhhbbbhbhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhelllllo
Well first you would substitute or plug in the values.
2(3+4+4)
Now we will follow the order of operations, or PEMDAS
2(11)=22
Your answer is 22
I think it would be B /C I’m so sooo sorry if I’m wrong but um I don’t take this math anymore :)
Answer:
a. the Student's t-distribution with 124 degrees of freedom
Step-by-step explanation:
We have no information about the standard deviation of the population, just for the sample, which means that the student's t-distribution is used.
Degrees of freedom
Sample size subtracted by 1.
125 households were sampled.
125 - 1 = 124 degrees of freedom.
So the correct answer is:
a. the Student's t-distribution with 124 degrees of freedom
