Question;1) Suppose you want to estimate the proportion of ALL Broward College students who are parents. There are close to 70,000 BC students and this is not information that is requested by the college, and is therefore not available on the student database. How would you go about obtaining your estimate?2) Suppose you take a survey of all students who attend class on a particular campus at 9:30 AM and find that 25% of those students are parents. Would you feel comfortable concluding that the proportion of all BC students who are parents is also 25%? Why or why not?3) Compare the following two statements. 1) I am 90% confident that the true proportion of all BC students who are parents is somewhere between 20% and 30%. 2) I am 100% confident that the true proportion of all BC students who are parents is somewhere between 0% and 100%. The second statement can be stated with higher confidence. But what is the trade-off?
