One Sample Hypothesis

One Sample guessing Testing November 03, 2010 One Sample opening Testing The basic premise of feasibleness testing is to prove or disprove a research stirment. By allowing an flaw ramble on of 5% or less, and conscription conclusions based on statistical principles, one can shut that the findings must be pure if chance alone could ingeminate the results 5% of the time or less. A shadowy possibility cannot be proven; a researcher can lonesome(prenominal) fail to reject it. If a researcher fails to reject a unimportant theory, they provisionally tell it, however an accepted hypothesis can be retested. in that location argon two tokens of possible errors when deciding the probability of a hypothesis. The first is a agree I error. A slip I occurs when a empty hypothesis is rejected pellucid though it is true. The second is a grammatical case II error. A type II error occurs when the researcher fails to reject a null hypothesis that is false. In most cases, the true attitude is unknown, as a result, the researchers are unaware they have attached an error. When rendering a conclusiveness on a null hypothesis, errors are likely to occur. just the probably of either type of error can be drastically reduced by gathering more shew (Doane & Seward, 2007, p. 348).

There is a fin step process that the researcher must conduct in order to answer some(prenominal) research question sustain an inferential statistical test. STATING THE seek QUESTION The first step in hypothesis testing is to state the research scenario as a question that identifies the nation of interest, the line of the variable, and the hypothesized value of the parameter. For example: The renown earnings for women in 2008 interpreted from the Wages and Wage Earners reading Set was less than $25,000 annually. The population of interest is the annual hire for women in 2008. The parameter is the implicate of the annual salaries of women in 2008. In this example, the salary is continuous, and the hypothesized value of the parameter, the mean, is $25,000.
