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
Answer:
D. Distributive Property
Step-by-step explanation
The example you have looks alot like it. Hope this helped :)
Area of the triangle = (1/2)*base* height = (1/2)*3*6 = 9 sm²
We have 4 triangles like this one ,
so area of 4 triangles = 9*4 = 36 cm².
Area of the square = 3*3 = 9 cm²
Surface area here means area all triangles + area of the square =36 +9 =
= 45 cm ²
Answer is 45 cm².
Data can be analysed in a situation when one wants to know how increase in price has an effect on purchasing power.
<h3>What is a trend?</h3>
It should be noted that a trend simply means the general direction or price over a period of time. A situation when I need data was when I wanted to know how increase in prices had an effect in one's purchasing power.
To get the data, I had to take the prices of goods when there was no inflation and prices when there was inflation and how they had an impact on income.
It showed that an inverse relationship existed as an increase in prices had a negative impact on one's purchasing ability.
