What happens to the confidence interval as the sample estimate increases?
Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase. In effect, the confidence interval will be translated to a higher value without any change in its size.Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase.

What is represenatative sample of population?
A representative sample is one where the statistics of the sample are the same as the statistics for the parent population.
When you draw a sample from a normal distribution what can you conclude about the sample distribution?
The answer depends on how the sample is selected. If it is a simple random sample, of size n, then it is distributed approximately normally with the same mean as the population mean.The answer depends on how the sample is selected.

What is it called when all the items in the population have the same chance of being selected for the sample?
a random sample
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
Which mineral contains iron has a metallic luster is hard and has the same color and streak?
Magnetite
Which mineral contain iron has a metallic luster is hard and has the same color and streak?
Magnetite
What mineral contains iron has metallic luster and has a streak that is the same color as the mineral?
Magnetite can be black and it has a black streak. It is metallic and iron ore
The Luster of gold jewelry is physical change?
yes, because when you shape gold into jewelry, it's luster is the same. it still has that shine on it. hope this helps you. :)
Does the density of a mineral depend on the size of the mineral sample?
No, to tell how hard a mineral is you either have to test it or determine what mineral it is. Testing uses materials of known hardness such as a fingernail, or copper penny, or scratch plate, if the mineral is scratched by whatever you use to test it is softer. Hardness however is not based on size it will be the same for any sample of the same rock no matter what the size because its based on atomic arrangement and bond type.
Why is the color of the mineral not a reliable test for the identity of a mineral?
Minerals can change color based on small impurities
What does not change when a physical change in a sample occurs?
Substance in the material Remain the same
What is the best way to identify a mineral?
Streak test because minerals can vary in color, size and shape but their streak color will always be the same for that specific mineral. Calcite comes in many shapes and colors, but its streak is always white.
Small amounts of different elements in the same mineral can change the what of the mineral?
colour, density and hardness.
Two minerals have the same color and luster what else could you use to identify the mineral?
Examples of mineral characteristics: - density - hardness - refractive index - chemical composition - magnetic properties - cleavage - crystal system - radioactivity
Would aluminium silicon and phosphorous have the same mass hardness luster or corrosiveness?
luster
What is the soils texture?
Soil Texture - measurement of the proportion of mineral particles of different sizes that are found in the same sample of soil (sand, silt, clay).
