Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Ms Best is a high school math teacher. Ms. Best has two sections of geometry. She teaches one section using a traditional approach. The second section Ms Best uses a tasked-based learning approach. The table below summarizes the descriptive statistics for the final exam. Ms Best concludes that the tasked-based learning approach students consistently scored higher than the traditional students. Is Ms Best conclusion correct? Why? Be very thorough in your response and use all the statistics reported and their interpretation to support your answer.
