30. Given the research question "Caninfant birth weight be predicted bymaternal weight and height?" During a 2years period an investigator assemblesdata on consecutive newborns in a largehospital. The study is limited to termnewborns defined by delivery 38-42weeks after the mother's last menstrualperiod. In the hospital ward, theinvestigator measures each infant's birthweight and the mother's weight andheight. Based on the data obtained, theinvestigator concludes that birth weightand height is strongly dependent on themother's weight.Do you agree or disagree withinvestigator's conclusion? Explain why orwhy not.

Given is a question based on correlation and regression analysis.

It's important to understand that hypothesis testing is just how statisticians (by "statisticians" I mean people who are working with data, e.g. analysts, auditors, economists, whoever) answer quanitative questions. We intuitively know that not much is truly certain, and that it's really hard (if not impossible) to collect data on everything we are curious about. So we use samples and try to extrapolate to a larger population. For this discussion, I would like each of you to come up with your own interesting hypothesis test. So, you will do the following: 1) Explain the context or story for which you have a problem stats might be able to help with. 2) Come up with the null and alternative hypotheses. This can be in words, or numbers, or a combination of both (I'll give an example below). 3) Explain where/how you might collect data to reach a conclusion for the test. 4) (RESPONSE) When you respond to someone else's post, I want you to critique their test and data. If you can, suggest a…
