Answer:
a glass of muddy water
Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.
Hope that helps.
Answer:
It is necessary to make the following assumptions when making inferences about a group of people based on a sample of subjects drawn from that group:
- Data is quantitative in nature.
- A sample size of 30 or more is required.
- The data set must consist of a simple random sample.
- A Normal Distribution must be present in the data.
The data must come from a sample that isn't all the same size so that it can be generalized well.
The sample size must be at least 30 or more, according to the central limit theorem.
Mean and standard deviation are two examples of quantitative data from which statistical conclusions can be drawn.
To avoid bias, the sample size should be increased rather than the distribution skewed.

Answer:
- Vitamin A (fat absorption/liver disorder): Dry skin (i.e. eczema)
- Vitamine B1 (thiamine deficiency): Beriberi (wet or dry)..wet affect heart/circulatory system, dry can cause heart failure
- Vitamin C (ascorbic acid): anemia, gum disease, skin problems, and scurvy
- Vitamin D (calcium): bone loss/density; i.e. Rickets where bones become soft and bendable
Mineral dificiency (when your body does not absord or obtain the required amount of intake)
- Iron (important for hemoglobin); low iron can cause anemia (causes you to feel weak or tired)
- calcium (important for strong bones/teeth, supports proper function for blood vessels, muscles, nerves, and hormones); Calcium deficiency disease is osteopenia (left untreated it leads to osteoporosis--usually in older adults)
