saw5 [17]

Step-by-step answer:

It is not clear what the question exactly wants, but here's the best I can do with possible interpretations.

Let P(t) = population t years after 2000, then

P(t) = (N0)e^(Rt)

where

N0=population of year 2000 = 19169000

R=rate of growth, in ratio = 0.006

e=base of natural logarithm = 2.7182818284...

Then

P(25) = 19169000*e^(0.006*25)

= 19169000*e^(0.15)

= 22271200.59885846

= 22271201

Not sure what it means "the other value", as we only have one.

Answer: The margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%)

Step-by-step explanation:

Given : A New York Times poll found that 47% of the women said they do not get enough time for themselves.

The poll announced a margin of error of ± 3% for 95% confidence in its conclusions.

A margin of error gives that value of percentage error of in results by which any random value will differ from the real population value.

Here the margin of error tells that the proportion of the a random sample women said they do not get enough time for themselves can be differ by ±3% than the estimated proportion (47%).
