I think this is the correct answer: * Zc x (sigma/sqrt of n)
c= .95 (Zc of 1.96)
0.711*
Hello, the correct answer would be B. Because if she had 250 then used 44 you would subtract 44 from 250 to find x
Hope this helps :)
Answer: z = -19.5
Step-by-step explanation:
-6.5 = z/3
-19.5 = z Multiply 3 to both sides
Since the bottom number is the same.
Multiply the top and bottom to get the answer 2/9
1*2=2
3*3=9
