5. Explain the sampling strategy and potential bias for the following situations. a. Bob is wondering about people that use the Love Library. Bob stands outside the library and asks people walking by into the library questions. b. Alice wants to know how 7th graders and 8th graders at Lemon Grove Middle school feel about mathematics they are learning. Alice gives numbers to each name of 7th and 8th graders learning mathematics. Alice uses these numbers to make an interval. With this interval, Alice uses a random number generator to produce the numbers, which will be associated to names. The names produced by this method will be the students Alice asks questions to. E. Bob wants to know certain things about people working for a company X. Bob goes to this ompany's location from 9am to 10am and asks every worker some questions. Bob also goes at pm to 5pm and asks every worker some questions. Sample tlatese

A family decides to go on a one-day excursion. For the day of the week, the family can choose to go on Friday(F) or Saturday(S). For the location, they can choose to go to an amusement park(A), the beach(B), the mountains(M), or the zoo(Z). The family decides to make the two choices at random. (a) Determine the number of sample points in the sample space (b) Construct a tree diagram and list the sample space. (c) Determine the probability that the family does not select Friday. Simplify as a fraction. (d) Determine the probability that the family selects Saturday and the zoo.

A bag contains 9 balls numbered 1 to 9. A ball is randomly selected. What is the sample space?
A community college has 7663 students currently enrolled in classes. To gain the students' opinions about an upcoming building project, the college president wishes to obtain a simple random sample of 8 students. He numbers the students from 1 to 7663. Complete parts (a) and (b) below. Click the icon to view the random number table. (a) Using the provided random number table, the president closes his eyes and drops his ink pen on the table. It points to the digit in row 2, column 4. Using this position as the starting point and proceeding downward, determine the numbers for the 8 students who will be included in the sample.
g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…
