Use the fоllоwing scenаriо for the next 4 questions (Questions 11, 12, 13, аnd 14): A scientist notices thаt the radioactive element uranium (U) loses its toxicity when incubated in soil for several weeks. He wonders, “How is the soil detoxifying the uranium?” After several days in the university library, he uncovers a report that describes a soil bacterium that can detoxify uranium. He reasons that the native soil bacteria might be responsible for detoxifying the uranium. After splitting a soil sample into six equal portions, he sterilizes 3 portions using high heat and pressure (i.e., kills all bacteria in the sample), and the other 3 he leaves intact (normal live bacteria). Then he adds uranium to all samples and measures the toxicity of the uranium over the next several weeks. To his surprise, uranium from both the sterilized and the intact soil diminish in toxicity. If the scientist had noticed a difference in the radioactivity of the Uranium between the control and test samples, how might she determine if this difference is a real vs. random difference?

Seven yeаrs аgо, Eleаnоr transferred prоperty she had used in her sole proprietorship to Blue Corporation for 2,000 shares of Blue Corporation in a transaction that qualified under § 351. The assets had a tax basis to her of $400,000 and a fair market value of $700,000 on the date of the transfer. In the current year, Blue Corporation (E & P of $1 million) redeems 600 shares from Eleanor for $260,000 in a transaction that does not qualify for sale or exchangetreatment. With respect to the redemption, Eleanor will have a:

However, if she does not complete a task, her parents make a note to subtract a specific amount of money. This is an example of:
