Professor Ramos advertises his diet program performed on 70 obese teenagers. Ramos weighed each of the 70 individuals before beginning the diet and then 6 weeks after starting the diet (just for the record and so you know, this is a two dependent sample experiment since the same population of 70 individuals is weighed before and after). He recorded the difference in weighs before and after. A positive value indicates a person lost weight on the diet while a negative value indicates the person gained weight while onthe diet. Hi program assured a 95% confidence interval for the average weight change while on the​ diet. After all the results Ramos computed his 95% confidence interval, coming to be ​(−​2, 7) in pounds. His claim is that his results show the diet works at reducing weight for obese teenagers since more people lost weight than gained weight. What conclusion can be made about the weight loss​ program? Make sure you explain thoroughly your thoughts

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
