85 out of a sample of 200 randomly poled individuals voted yes on a particular ballot measure.

a. Construct a 90% condence level for the true population proportion.

b. Construct a 99:5% CI for the same group.

2. Among the 2,134 workers surveyed, 47 percent of college students graduates did not find a job that was related to their college major. What's more, 32 percent college grads said that they had never worked in a job related to their major.
