A ________ is a set of assumptions about how sample data are selected and about the population from which the sample data are selected.
Homework Answers
A statistical model is a set of assumptions about how sample data are selected and about the population from which the sample data are selected.
Note: a statistical model is a mathematical model that embodies a set of statistical assumptions concerning the generation of some sample data and similar data from a larger population.

When n-1 is used in the denominator to compute variance the data set is a sample. the data set is a population. the data set could be either a sample or a population. the data set is from a census. For any distribution, statements about the proportion of data values that must be within a specified number of standard deviations of the mean can be made using Chebyshev's theorem.

An economic model is developed from a set of assumptions about consumer behavior and predicts that people will buy less of a good the higher the price of the good. Empirical testing of this model would involve O O A. checking the assumptions carefully to make sure that they realistically depict human behavior.

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are nequals=195 x overbarxequals=5.84 sequals=2.21 Use a 0.10 significance level to test the claim that the population mean of such ratings is less than 6.00 Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n=186, x overbarxequals=6.536.53, s=1.971.97. Use a 0.05 significance level to test the claim that the population mean of such ratings is less than 7.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses?

Which of the following is NOT an assumption about nonparametric tests? a.They do not involve the estimation of population parameters. b.The expected frequencies are based on the row and column frequencies for a sample rather than on assumptions regarding how frequencies for the two variables are distributed in the population c. Data from a sample is being used to estimate the population parameter. d.They do not require variables to be normally distributed.
