Why is a large sample better than a small sample?
A large sample will reduce the effects of random variations.
How is the process of determining percentiles different if you were given a sample mean rather than individual raw score?
It is impossible to determine the percentiles if you are given only the sample mean since percentiles are a measure of the spread of the data; the mean gives no information on that.
When the sample size is greater than n equals 30?
There is nothing particularly significant about a sample size of 30.
Is sample standard deviation the same as standard deviation?
No, the standard deviation is a measure of the entire population. The sample standard deviation is an unbiased estimator of the population. It is different in notation and is written as 's' as opposed to the greek letter sigma. Mathematically the difference is a factor of n/(n-1) in the variance of the sample. As you can see the value is greater than 1 so it will increase the value you get for your sample mean. Essentially, this covers for the fact that you are unlikely to obtain the full population variation when you sample.
What is the probability of a sample mean being less than 12752 or greater than 12755?
sample n equals 37 sorry and if you could write the equation that would be helpful
Which property of sample of mercury is different at 320 kelvin than at 300 kelvin?
The vapor pressure of mercury at 320 K would be higher than at 300 K. Mercury is a liquid metal that has a higher vapor pressure at higher temperatures, resulting in more mercury vapor in the sample at 320 K compared to 300 K.
Why does density not depend on the size of the sample?
Density is an intensive rather than extensive property.
How is Mercury is different from Jupiter?
Mercury is muich smaller than Jupiter, is sold rather than gasseous, is closer to the sun and has no moons.
Will a solid piece of iron float in a sample of mercury?
Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
Why is an oxygen atom a different element than a mercury atom?
The number of protons is different.
How is Mercury different than any other planet?
It is the nearest to the sun.
How are mercury and Pluto different?
While the planet Mercury and Pluto have some similarities, they are quite different. Mercury is much warmer than Pluto because of its proximity to the sun. The year on Mercury is 88 days compared to 248 years for Pluto.
How is real property different from personal property?
The difference between personal property and real property is that personal property can depreciate faster than improvement made on real property.
Which property of a coin is different on the moon than it is on earth?
Mass
Will neptunium float or sink in mercury?
The accepted average density of Neptunium is 19.38 g/cm3 (it is radioactive with several isotopes with somewhat different inherent densities) The average density of Mercury is 13.534 g/cm3 Since Neptunium is more dense than Mercury a sample would be expected to sink in Mercury
A 7.40 cm3 sample of mercury has a mass of 102 g will it float in water?
No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
Why does hydrogen emit different wavelengths of light than mercury?
Hydrogen emits different wavelengths of light than mercury because each element has a unique arrangement of electrons in its atoms. When electrons in hydrogen atoms move between energy levels, they emit specific wavelengths of light. In contrast, mercury atoms have different electron configurations, leading to the emission of different wavelengths of light.
