Answer:
(b) 4,445
Step-by-step explanation:
If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?
Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)
So n=(Z/E)^2*p*(1-p)
=(1.96/0.015)^2*0.5*0.5
=4268.444
Take n=4269
Answer:(b) 4,445
The answer is [-4,6)
Graph both the you can easily find the answer
The correlation is positive, negative and no correlation.
Thats uhhhhhh..... thats pretty cool.
-14a-5=-12
+5 +5
-14a=-7
Divide -7 by -14a
a=2
