Population in 2016 = 7.4 billion
Population in 2017 \(\displaystyle={7.4}\times\frac{{{100}+{1.1}}}{{100}}\), so
Population in 2020 \(\displaystyle={7.4}\times\frac{{\left({100}+{1.1}\right)}^{{4}}}{{100}^{{4}}}=\)
\(\displaystyle={7.4}\times{1.011}^{{4}}={7.73}\) billion

A random sample of 100 automobile owners in the state of Virginia shows that an automobile is driven on average 23,500 kilometers per year with a standard deviation of 3900 kilometers.
Assume the distribution of measurements to be approximately normal.
a) Construct a \(\displaystyle{99}\%\) confidence interval for the average number of kilometers an automobile is driven annually in Virginia.
b) What can we assert with \(\displaystyle{99}\%\) confidence about the possible size of our error if we estimate the average number of kilometers driven by car owners in Virginia to be 23,500 kilometers per year?

As of October, 2016 the world`s largest pumpkin weighed 1190 kilograms. In order to grow a record-setting pumpkin, the fruits mass must increase by an average of \(1.27ft^3/day\). If we assume that the dinsity of raw pumpkin is approximately \(0.50g/cm^3\) we can convert this to an increase in volume of \(1.27ft^3/day\). Question: If the volume of a spherical pumpkinn is increasing at \(\frac{1}{27}ft^3/day\), then how fast is the surface area of the pumpkin changing when the diameter of the pumpkin is b ft?
Give your answer with two decimal places, and ensure that you include unots.
Note: Equations for the volume and surface area of a sphere are on D2L in several places.

Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to estimate its average number of unoccupied seats per flight over the past year. To accomplish this, the records of 200 flights are randomly selected and the number of unoccupied seats is noted for each of the sampled flights. The sample mean is 11.6 seats and the sample standard deviation is 4.3 seats. \(\displaystyle{s}_{{{x}}}=?,\ {n}=?,\ {n}-{1}=?\). Construct a \(\displaystyle{92}\%\) confidence interval for the population average number of unoccupied seats per flight. (State the confidence interval. (Round your answers to two decimal places.)

The population P (in thousands) of Tallahassee, Florida, from 2000 through 2014 can be modeled by \(P = 150.9e^{kt},\) where t represents the year, with \(t = 0\) corresponding to 2000. In 2005, the population of Tallahassee was about 163,075.
(a) Find the value of k. Is the population increasing or decreasing? Explain.
(b) Use the model to predict the populations of Tallahassee in 2020 and 2025. Are the results reasonable? Explain.
(c) According to the model, during what year will the — populates reach 200,000?

In a random sample of 24 people, the mean commute time to work was 33.7 minutes and the standard deviation was 7.1 minutes. What is the margin of error of \(\displaystyle\mu\)?
Interpret the results.
A) With \(\displaystyle{90}\%\) confidence, it can be said that the population mean commute time as between the bounds of the confidence interval.
B) It can be said that \(\displaystyle{90}\%\) of people have a commute time is between the bounds of the confidense interval
C) With \(\displaystyle{90}\%\) confidence, it can be said that the commute time is between the bounds of the confidence interval.
D) If a large sample of people are taken approximately \(\displaystyle{90}\%\) of them will have commute times between the bounds of the confidence interval.
