Answer: B) The width of the interval based on 100 men would be about three times the width of the interval based on 900 men.
Explanation:
Based on the information given, if there's no change in the sample proportion, the option that best describes the anticipated effect on the width of the confidence interval assuming the magazine surveyed a random sample of 100 men who practice yoga, rather than 900 men will be option B "The width of the interval based on 100 men would be about three times the width of the interval based on 900 men.
Therefore, the correct option is B.
They would be concerned becuase they affect they area with the symptoms/problems and they would aid them because they are most ways common symptoms are found and usually help find more problems
I think it 2 but im not sure
i hope this helps
Answer
B) 2041
Explanation:
The rate of growth per year is 1.2% which means after first year the population will be
7+ 7×(1.2/100)
After second year
7×1.012 +7×1.012 (1.2/100)
=7×1.012 (1+1.2/100)
=7×1.012 (1.012)
=7×1.012 ×1.012
Similarly, after third year it will be as:
=7×1.012 ×1.012 ×1.012
So our after x year the growth will be
7 (1.012)^x
We need to find, when the value will be 10 billion so our equation will be as:
10=7×(1.012)^x
We can solve it easily here.
10/7= (1.012)^x
Take log on both sides
㏒ 10/7 = ㏒(1.012^x)
㏒ 10/7 = ㏒(1.012^x)
㏒ 10/7 ÷㏒(1.012) = x
x =29.90 ≈ 30
Conclusion:
So it will take 30 years to take the world population to reach 10 billion if the rate of growth is 1.2%. Thus 2011 + 30 = 2041 is the correct answer.
