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)

What are the luster cleavage hardness and color of rocks?

Luster refers to the way light interacts with the surface of a mineral. Cleavage is the way a mineral breaks along planes of weakness. Hardness is the resistance of a mineral to scratching. Color is the visual appearance of a mineral, which can vary widely within the same mineral species.


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.


What does not change when a physical change in a sample occurs?

Substance in the material Remain the same


What mineral property is the least useful property?

Luster is typically considered the least useful mineral property, as it does not provide much information about the mineral's identity or composition. Luster simply describes how light is reflected off the surface of a mineral, such as metallic, glassy, or dull, and can vary even within the same mineral species.


Is it true that the larger the sample of a mineral the greater its density?

No, the density of a mineral remains constant regardless of the size of the sample. Density is an intrinsic property of the mineral and is determined by its composition and structure. It is typically expressed in units of mass/volume, so a larger sample will have a proportionally greater mass and volume, resulting in the same density.


The Luster of gold jewelry is physical change?

Yes, the luster of gold jewelry is a physical change because it does not alter the chemical composition of the gold. It is simply a change in its appearance due to polishing or cleaning, which can be reversed without affecting the gold's properties.


Small amounts of different elements in the same mineral can change the what of the mineral?

The small amounts of different elements in a mineral can change its color, hardness, and other physical properties.


What is the best way to identify a mineral?

The best way to identify a mineral is through a combination of physical properties such as color, hardness, luster, cleavage, and specific gravity. Using a mineral identification guide or performing tests like streak and acid tests can also help in determining the unique characteristics of a mineral. Additionally, seeking professional assistance from a geologist or mineralogist can provide accurate and reliable identification results.


What two properties are least useful in identifying a mineral?

Color and luster are often the least useful properties in identifying a mineral since these characteristics can vary widely within the same mineral species.
