Answer:
Step-by-step explanation:
Total number of marbles = 5 + 2 + 3 = 10
Probability of choosing 1 green marble = 2/10
Probability of choosing 1 yellow marble = 3/10
Notice (and this is important) that the denominator didn't change. Why?
Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.
So what is the probability of P(green then yellow)?
P(green then yellow) = 3/10 * 2/10 = 6/100
Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.
the answer to 54,000 x 10 is 540,000

Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that
against the alternatives 
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis 
, then P value is
![P = 2[1- \phi(\left | Zc \right |)]](https://tex.z-dn.net/?f=P%20%3D%202%5B1-%20%5Cphi%28%5Cleft%20%7C%20Zc%20%5Cright%20%7C%29%5D%20)

B) significance level 
from 1st equation we get
Therefore 
FROM Z TABLE
C) significance level 
from 1 eq we get
Therefore
