Checkpoint 2 and Checkpoint 3 Visualizing CONFIDENCE INTERVALS Visualizing Hypothesis Testing Visualizing CONFIDENCE INTERVALS We estimate a population parameter using a sample statistics. Ex: Each group is working with a sample of data from a population Since such statistics vary from sample to sample, we need an idea how far the population is from the sample statistics ==> a MARGIN of ERROR. a range of plausible values for the population parameter ==> an INTERVAL ESTIMATE When we construct this interval using a method that has some predetermined chance of capturing the true parameter, we get a confidence interval .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
