### Teaching Methods A class of 30 computer science students were taught an introductory computer programming class with an innovative teaching method that used a graphical interface and drag-and-drop methods of creating computer programs. At the end of the class, 23 of these students said that they felt confident in their ability to write computer programs. Another class of 40 students were taught the same material using a standard method. At the end of the class, 25 of these students said they felt confident. Assume that each class contained a simple random sample of students. Construct a 95% confidence interval for the difference between the proportions of students who felt confident. #### Tasks (a) **List all variables given and the calculator program.** (b) **Find the point estimate.** (c) **Find the margin of error.** (d) **List the confidence interval.** (e) **Interpret the confidence interval.**
