In nutrition, the recommended daily allowance of vitamins is a number set by the government as a guide to an individual's daily vitamin intake. Actually, vitaminneeds vary drastically from person to person, but the needs are very closely approximated by a normal curve. To calculate the recommended daily allowance, thegovernment first finds the average need for vitamins among people in the population, and the standard deviation. The recommended daily allowance is then definedas the mean plus 2.5 times the standard deviation.What is the recommended daily allowance for a vitamin with mean u and standard deviation o?recommended daily allowance =

Supppse μ is the mean and σ is the standard deviation. Population is normally distributed.

Answered: In nutrition, the recommended daily…

Calcium is essential to tree growth because it promotes the formation of wood and maintains cell walls. In 1990, the concentration of calcium in precipitation in a certain area was 0.15 milligrams per liter (mg/L). A random sample of 10 precipitation dates in 2007 results in the following data table. Complete parts (a) through (c) below. Click the icon to view the data table. (a) State the hypotheses for determining if the mean concentration of calcium precipitation has changed since 1990. Ho.
