**Example 1:** A survey conducted with 80 randomly selected (r/s) California State University students reveals that 52 of them are employed. In a separate survey of 40 University of California students, it is found that 20 are employed. Construct a 95% confidence interval (c.i.) for the difference between the overall employment percentage of CSU students and UC students.

It is given that For sample 1: Favourable cases, X1 = 52 Sample size, n1 = 80 For sample 2:…
