Answer:
As a general rule of thumb, a small confidence interval is better. The confidence interval will narrow as your sample size increases, which is why a larger sample is always preferred. As our page on sampling and sample design explains, your ideal experiment would involve the whole population, but this is not usually possible.

j/4 <4+8
j/4 <12
j <12.4
j <48
I think this is a repeat question from yesterday.
f(x)=3x+1
g(x)=x^2-1
f o g (x) = f(g(x))=f(x^2-1)=3((x^2-1))+1=3x^2-3+1=3x^2-2
f o g(2)=3(2^2)-2=3(4)-2=10
Answer:
y = -10
Step-by-step explanation:
Hey there!
To solve this you first have to distribute the -3 to y and 5. When you do this you get...
-3y - 15 = 15
Add 15 on both sides you get...
-3y = 30
Divide by -3 and you get...
y = -10
Hope this helped :)
