This module introduces Hypothesis Testing. Ĝonfidence Interval for a Population Proportion.Towards the close of module we start introducing the concept of Hypothesis Testing. We also introduce with an application, the confidence interval for a population proportion. This module presents various business applications of the confidence interval including an application where we use the confidence interval to calculate an appropriate sample size. Module 2: Confidence Interval - Applications Ĝonstructing a Confidence Interval using z-statistic and t-statistic.Ĝonceptual understanding of a Confidence Interval.Introducing the t-distribution, the T.DIST and T.INV excel functions.

We will then use these building blocks to construct confidence intervals. We will introduce the various building blocks for the confidence interval such as the t-distribution, the t-statistic, the z-statistic and their various excel formulas. In this module you will get to conceptually understand what a confidence interval is and how is its constructed. Module 1: Confidence Interval - Introduction Please note that earlier versions of Microsoft Excel (2007 and earlier) will not be compatible to some Excel functions covered in this course. To successfully complete course assignments, students must have access to a Windows version of Microsoft Excel 2010 or later.

These are done by easy to understand applications. We then introduce various calculations to constructing confidence intervals and to conduct different kinds of Hypothesis Tests.

We first conceptually understand these tools and their business application. This is the third course in the specialization "Business Statistics and Analysis" and the course advances your knowledge about Business Statistics by introducing you to Confidence Intervals and Hypothesis Testing. A mastery over these topics will help enhance your business decision making and allow you to understand and measure the extent of ‘risk’ or ‘uncertainty’ in various business processes. Confidence intervals and Hypothesis tests are very important tools in the Business Statistics toolbox.
