What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
What is used to estimate the population parameter?
point estimate
When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
How can correlation and regression analysis be used to make strategic decisions in a dynamic competitive business environment filled with risk and uncertainty.?
Correlation and regression analysis can help business to investigate the determinants of key variables such as their sales. Variations in a companies sales are likely to be related to variation in product prices,consumers,incomes,tastes and preference's multiple regression analysis can be used to investigate the nature of this relationship and correlation analysis can be used to test the goodness of fit. Regression can also be used to estimate the trend in a time series to make forecast
What is an example of a statistic?
99% of all statistics are made up. Sex Panther is a cologne that works 50% of the time, all the time. As of a recent 2011 estimate, the United States currently holds about 4.48% of the world's population.
What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex
What is the the relationship between population and sample parameter and statistic?
The relations depend on what measures. The sample mean is an unbiased estimate for the population mean, with maximum likelihood. The sample maximum is a lower bound for the population maximum.
What is the statistic that is used to estimate a population standard deviation?
the sample standard deviation
Is the sample mean a point estimate of the population mean?
A point estimate of a population parameter is a single value of a statistic. For example, the sample mean x is a point estimate of the population mean μ. Similarly, the sample proportion p is a point estimate of the population proportion P.
What is the purpose of a sampling distribution?
A statistic based on a sample is an estimate of some population characteristic. However, samples will differ and so the statistic - which is based on the sample - will take different values. The sampling distribution gives an indication of ho accurate the sample statistic is to its population counterpart.
The proportion of the variation in the dependent variable y that is explained by the estimated regression equation is measured by the?
confidence interval estimate
How can one determine the uncertainty of the slope when finding the regression line for a set of data points?
To determine the uncertainty of the slope when finding the regression line for a set of data points, you can calculate the standard error of the slope. This involves using statistical methods to estimate how much the slope of the regression line may vary if the data were collected again. The standard error of the slope provides a measure of the uncertainty or variability in the slope estimate.
What is the total population of Israel and Jordan?
Population of Israel: 2008 estimate 7,282,000 Population of Jordan: 2007 estimate 6,053,193
What is the importance of correlation and regression analysis in business decision making?
