In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of one year. which equation shows how to calculate the population growth rate of this population?
a. 0.50 + 0.20 = 0.70
b. 0.20 - 0.50 = -0.30
c. 0.50 - 0.20 = 0.30
d. 0.20 x 0.50 = 1.00

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;
