In inferential statistics, specifically in hypothesis testing, there are two contending hypotheses: the null hypothesis (h0) and the alternative hypothesis (), in which the objective is to gather evidence through sampling that would either support or reject one of the hypotheses. Descriptive statistics are used to summarize data learn about the different kinds of descriptive statistics, the ways in which they differ from inferential statistics, how they are calculated.

In statistics, we often rely on a sample--- that is, a small subset of a larger set of data --- to draw inferences about the larger set the larger set is known as the population from which the sample is drawn.

The calculation of inferential statistics in these studies is only justifiable if researchers can be assured that the findings from their institution are similar to the reference population.
In the t-test, the degrees of freedom is the sum of the persons in both groups minus 2 given the alpha level, the df, and the t-value, you can look the t-value up in a standard table of significance (available as an appendix in the back of most statistics texts) to determine whether the t-value is large enough to be significant. Inferential statistics and findings create an inferential statistics (hypothesis) test using the research question and two variables your learning team developed for the week 2 business research project part 1 assignment.
