Question

A group of 50 computer science students were taught 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, 43 of these students said
that they felt confident in their ability to write computer programs. Another group of 40
students were taught the same material using a standard method. At the end of class, 25 of
these students said they felt confident. Assume that each class contained a simple random
sample of students. Find a 99% confidence interval for the difference between the
proportions of students who felt confident.
