Some government leaders propose allowing oil companies to drill in currently protected lands that may be rich in oil reserves. Environmental researchers argue that drilling in such lands would be harmful to the surrounding
ecosystem. To measure support for drilling in such lands, an oil company representative uses random-digit
telephone dialing to contact adults in the region and measure opinion for increased drilling. One question in the
survey asks, "Given that an increase in drilling could result in increased tax revenue and additional jobs to the
region, would you support a proposal to allow drilling in lands currently protected from drilling?" What type of bias
could be most likely affecting the survey results?
O This is undercoverage bias because some segments of the population will be excluded from the sample.
O This is response bias because those selected for the survey may not provide truthful opinions about oil drilling
O This is voluntary response bias because those most passionate about drilling will be more likely to register an
opinion
O This is question wording bias because the information given at the start of the question may lead those surveyed
towards a desired response

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
