The composition of the earth's atmosphere may have changed over time. to try to discover the nature of the atmosphere long ago, we can examine the gas in bubbles inside ancient amber. amber is tree resin that has hardened and been trapped in rocks. the gas in bubbles within amber should be a sample of the atmosphere at the time the amber was formed. measurements on specimens of amber from the late cretaceous era (75 to 95 million years ago) give these percents of nitrogen: 63.4 65.0 64.4 63.3 54.8 64.5 60.8 49.1 51.0 assume (this is not yet agreed on by experts) that these observations are an srs from the late cretaceous atmosphere. use a 96% confidence interval to estimate the mean percent of nitrogen in ancient air. % to %

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
