What is the mean of the sampling distribution equal to?
The mean of the sampling distribution is the population mean.
Can Lorenz curve above the diagonal?
No.The Lorenz curve measures inequality of distribution of income (or wealth). The diagonal represents a distribution that is perfectly equal and you cannot get more equal than that!
When the population standard deviation is unknown the sampling distribution is equal to what?
The answer will depend on the underlying distribution for the variable. You may not simply assume that the distribution is normal.
What is the distribution of values taken by a statistic in all possible samples of equal size from the same population?
It is the sampling distribution of that variable.
The mean of a sampling distribution is equal to the mean of the underlying population?
This is the Central Limit Theorem.
Do Saudi Arabia have equal distribution of income?
No, Saudi Arabia does not have equal distribution of income. There is a significant income inequality in the country, with a small percentage of the population holding a large share of the wealth while a larger portion of the population faces financial challenges.
Is the F distribution used to test whether two samples are from population with equal variances?
It can be used for that purpose.
Is normal distribution function has equal mean and variance?
In a normal distribution, the mean and variance are not inherently equal; they are independent parameters. The mean indicates the center of the distribution, while the variance measures the spread or dispersion of the data. However, in a specific case where the mean is set to zero (0) and the variance is set to one (1), they can be equal in value, but this is not a general characteristic of all normal distributions.
True or false a distribution of sample means is normally distributed with a mean equal to the population mean and standard deviation equal to the standard error of the mean?
True.
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
What is the population density and distribution for Portugal?
10,486.22 this is the density population and this is the distribution population 2,00465.789
What is population distribution usually greatly affected by?
Population distribution is usually greatly affected by what?
