What is a sample of viscosity?
For example the viscosity of water.
Will Random sample always accurately predict the outcomes of an entire population?
No. Only a census can ACCURATELY predict the outcomes: a random sample cannot.
Why As the temperature of oil sample decreases?
As the temperature of an oil sample decreases, its viscosity typically increases, meaning the oil becomes thicker and flows less easily. This change in viscosity can affect the oil's performance in applications such as lubrication or fuel. Additionally, lower temperatures can lead to increased wax formation in certain oils, which may further impact their behavior and usability. Overall, the physical and chemical properties of the oil can significantly change with temperature variations.

Which sample was removed during surgery and sent to a pathologist to be examined under a microscope?

Is melting a sample of gold an example of a physical or chemical change?
Melting a sample of gold is an example of a physical change.
In a sample of 75 randomly selected students at a school 30 are female. There are 1000 students in the school. Using these results predict the number of females in the school.In a sample of 75 randoml?
To predict the number of females in the school, we can use the proportion of females from the sample. In the sample, 30 out of 75 students are female, which is 40%. Applying this percentage to the total student population of 1000, we estimate that there are approximately 400 females in the school (0.40 * 1000 = 400).
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
