Each day, the number of births in the world is 84 thousand less than three times the number of deaths.
a.
If the population increase in a single day is 228 thousand
determine the number of births and deaths per day.
b. If the population increase in a single day is 228 thousand
by how many millions of people does the worldwide
population increase each year? Round to the nearest
million.
C.
Based on your answer to part (b), approximately how
many years does it take fur the population of the world
to increase by an amount greater than the entire US.

the answer is c.

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
