TrialOutcomesNumber of pairs with at least one extrovert1(3, 2) = (In, In) (2, 3) = (In, In) (6, 1) = (Ex, In) (2, 6) = (In, Ex) (8, 3) = (Am, In) (4, 1) = (Ex, In) (9, 4) = (Am, Ex) (9, 9) = (Am, Am)42(In, Am) (Am, Ex) (Am, Am) (Am, In) (Ex, Ex) (In, Am) (Ex, In) (Ex, Ex)43(Am, Ex) (In, Am) (In, Am) (Am, Am) (Ex, In) (Ex, Am) (Ex, In) (In, Ex)54(Ex, Ex) (Ex, Am) (In, In) (Am, Am) (Am, Am) (Am, Ex) (Am, Ex) (Ex, Ex)5a. Use the middle column from the table to estimate the average number of pairs in which both persons are extroverts.b. Use the middle column from the table to estimate the average number of pairs in which neither person is an extrovert.Q2. (3 points)Suppose, on the average, one out of every eight houses will experience some sort of crime in a certain neighborhood. What would be a way to model the 1/8 chance using only a coin? (Refer back to how you used a coin in the original plastic bag example in Section 4.2.)Q3. (2 points)Recall Example 4.5 in Section 4.2, where researchers were choosing people for a psychological experiment. There we assumed that 1/3 of all people are extroverts. Once again, eight pairs are drawn for a total of 16 people, but this time researchers draw each pair from within a family (that is, two people from each of eight families). In this experiment, the researchers found that the average number of pairs in which both are extroverts is 2.2.In Exercise 2 in Section 4.2 you estimated the number of pairs out of the eight in which both are extroverts, and your answer should have been less than 2.2. How can this difference be explained? What assumptions were we making when working with that example previously?Q4. (2 points)Over his career, a basketball player has scored on 1210 free throws and missed 214. What is his estimated probability of making a free throw?Q5. (2 points)A student thinks that statistical regularity means a guarantee that as the number of trials increases the relative frequency always gets closer to the theoretical probability. Examine Table 5.1 closely and agree or disagree with this claim.Q6. (2 points)Describe how you could use a random number table to model an event that has a probability of 1 in 1000 of occurring.Q7. (5 points)The probability of getting an A on your next test is 2/3; the probability of winning the door prize at the dance is 1/100; and the probability that your best friend will visit you next weekend is 1/5. What is the probability that all three events happen? What assumptions did you make? Do they seem reasonable?Q8. (6 points)A student has to match three terms that she has never seen before with their definitions. If she guesses, what is the probability of hera. Getting all three correct?b. Getting none correct?c. Getting exactly one correct?d. Getting exactly two correct?What assumptions did you make? Do they seem reasonable?If you need additional information referred to, let me know and I will send it to you. Thank you.
Hi,When do you need the answers ??Also I need some info Steve
I need the answers by 9pm cst today. And I am attaching
Hi again,I can do all of them but not Q5 and Q6 (i am not so good on "writing" questions)Is that ok for you ?Steve
yeah, that's fine!
Ok, and can you clarify which is the first column of the table ?? in question 1Steve
Do not worry, i understand question 1 nowSteve
I have absolutely no idea what they are referring to when mentioning column 1. I'm sorry, but I really must defer to you. Please do the best you can and I will attach some of the proceeding materials in the event that it will shed some light.
ps. I also have some questions for next week once you have completed these. Thanks again!
Ok, i am working on the set now (questions 1,2,3,4,7 and 8)I will post them shortly (less than 1 hour)Steve
Great you are the best.
I couldn´t do Q3 but if you can upload table 5.1 maybe i can do Q5let me knowSteve
Here are the answers but try to upload table 5.1ThanksSteve
Relist: Incomplete answer.Steve was GREAT!!!!! But, there were a couple of questions he was unable to answer. Here they are:Q5. (2 points)A student thinks that statistical regularity means a guarantee that as the number of trials increases the relative frequency always gets closer to the theoretical probability. Examine Table 5.1 closely and agree or disagree with this claim.Q6. (2 points)Describe how you could use a random number table to model an event that has a probability of 1 in 1000 of occurring.
Hi,If you upload table 5.1 maybe i can help with q 5)Steve
Here is table 5.1
OK, I am doing question 5)I appreciate if you accept my work ( i didn´t do q3 and q6)Steve
Great thank you very much. Can you send Q 3 and 6 to others. Thanks again!
