Boston College is doing an alumni donation drive. You are cold calling alumni and offering them a free BC fleece for donations of just $5 or more. The probability of success is 60 percent. (Most of the unsuccessful outcomes are immediate hang ups.) During an hour, you usually call 25 people. Each alumni represents an independent outcome.

You are interning for a political pollster. He is convinced that the proportion of people who will vote for the incumbent Congressman is 51 percent. For the rest of this question we will assume he is correct. If he chooses a sample of 400 people, what is the probability that his poll will show the incumbent Congressman with greater than 50 percent of the votes?

Use the STATA output at the end of this handout to answer the following questions. Respondents are a random sample of 616 workers. Model 1 [13 pts] Model 1 estimates the following model: ln(annearn)i = 0 + 1malei + "i

We are trying to figure out the proportion of our Congressional district voters that support re-electing the Congresswoman. We sample 1000 people and find that only 49% of our sample favors re-electing her. i. Find a 95% confidence interval estimate of the true population proportion that favors the Congresswoman. (10 pts) ⇒ We do not know the true p, hence we do not know the V ar(ˆp). But we can estimate it using ˆ

Wonder-Stats University was named the top party school globally. Your boss at a local newspaper can’t believe it. He asks you to go down to the university and investigate. You stand in front of the library and randomly select ten students that pass by. Then, you ask them how many hours they partied during the last week. (The week of the sampling was the week just prior to the mid-semester break.) The ten responses are presented in the xi column.

Suppose you roll a pair of dice, and take the sum. Let A be the event that you observe an even number. Let B be the event that you observe a number less than seven. Begin by writing down the two sets A & B as well as the sample space. The sample space is all possible sums that you can generate after rolling a pair of dice. ⇒ Sample space = S = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} A = {2, 4, 6, 8, 10, 12} B = {2, 3, 4, 5, 6} i. What is the intersection of A & B? What is the complement o...

In Super Mario Bros., there are eight worlds and each world has four levels. Boston College decided to hold a study break for students. The proportion of students who reached the respective levels in World 1 are as follows: Level 1 2 3 4 P(x) 0.5 0.3 0.1 0.1 i. Write down the cumulative probability distribution. )
