Introduction to Mathematical Statistics6th EditionAllen Craig, Joseph W. McKean, Robert V. Hogg 1,029 solutions What is the confidence interval estimate of the population mean quizlet?A 99% confidence interval estimate of the population mean can be interpreted to mean that we have 99% confidence that the true population mean will fall within the confidence interval estimate.
What is a mathematical technique for comparing the sample statistic with the null hypothesis using the standard error as a baseline?A test statistic is a mathematical technique for comparing the sample statistic with the null hypothesis, using the standard error as a baseline. A Type I error occurs when a researcher finds evidence for a significant result when, in fact, there is no effect (no relationship) in the population.
Is a method that help researchers organize summarize and simplify the results obtained from research studies?Descriptive statistics allow a researcher to quantify and describe the basic characteristics of a data set. As such, descriptive statistics serve as a starting point for data analysis, allowing researchers to organize, simplify, and summarize data.
What is a summary value that describes a population?A parameter is a summary measure that is computed to describe a characteristic of an entire population. (P - parameter, P-population) A statistic is a summary measure that is computer to describe a characteristic from only a sample of the population. (
