1. What is Hypothesis testing in Business Intelligence?
Hypothesis Testing – is used to prove or disprove the research (Business proposed decision) hypothesis by providing more measurable or concrete hypothesis statement. for example, a research hypothesis could be that the stock market index reflects the state of monsoon in the country. A statistical hypothesis might look at the values of the index with the percentage increase or decrease in rainfall during the year compared to previous years. Hypothesis Testing is a study about * How to test a sample against a benchmark? * How to assess the risk of incorrect decisions?
Identifying the confidence intervals for a decision-required item does these.
2. Statistical Hypothesis Testing – Inferences drawn in Business – and Predictive Analysis made for Business
Inferences – Inferential statistics is the term given to the branch of statistics that uses the information from the sample to infer the information about the population. For example, given a sample mean , the population mean (also called a parameter) can be determined using inferential statistics.
