    Details: Using AIU's large database of survey responses from the AIU data set, complete the following:

    Perform hypothesis testing on one variable's data. (Choose either the intrinsic or extrinsic column.) Perform a t-test by formulating a null and an alternative statement, choosing an acceptable significance value, determining the appropriate critical value, selecting the test statistic and determining its value from the sample data, comparing the observed value to the critical value obtained and determining whether to reject or fail to reject the null hypothesis.

    In a separate paragraph, provide some information on when to use a t-test and when to use a z-test and why. Also, provide some information about why samples are used instead of populations.

    Be sure to provide references in APA format for any resource you may use.

    //In this discussion, we are including the 'Concept of Hypothesis Testing'. This is done in the concern of the AIU's database. With the concept of the hypothesis, the initial discussion is also including some types of hypothesis testing; such as null hypothesis and alternative hypothesis.// Hypothesis Testing

    With the assistance of the survey responses from the AIU data set, the data about different variables has been observed for a specified sample. In this paper, the variable extrinsic job satisfaction will be analyzed by applying Hypothesis Testing. Hypothesis mainly refers to the assertion, which provides explanation about some condition or event (Bernstein & Bernstein, 1999). For statistical analysis of data, it is essential to formulate the Hypothesis to be tested about the data. The Hypothesis for the paper will assist in analyzing the extrinsic job satisfaction effectively.

    Null Hypothesis: It represents the statement that is considered as a basis for the argument about certain condition. The Null Hypothesis for the paper is:

    H0: It is considered that average extrinsic job satisfaction = 5.0

    H0: μ = 5.0

    Alternative Hypothesis: It represents the statement that is considered as a basis for the argument in case of rejection of Null Hypothesis. The ...
