A community college has 7654 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 7654. Complete parts (a) and (b) below. (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. The numbers for the students are _____________. (b) The president uses technology to produce the following random numbers. 6647, 7546, 5135, 795, 1216, 7546, 2732, 5137, 7350, 5135 Determine the numbers for 8 students who will be included in the sample.

In a memory test, the test subjects are given a large number and are asked to memorize it. Historical records show that 80% of test subjects pass the test. To pass the test, a subject must exactly repeat all the digits in the number after two hours. A random sample of 625 people to take the memory test is going to be chosen. Let p be the proportion of people in the sample who pass the test. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of P. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(P >0.84), which is the probability that more than 84% of the people in the sample pass the test. Round your answer to four decimal places. 0 X
A farmer sows 100 seeds of a new type of corn and wants to quickly determine the yield, or total number of ears of corn, for the crop when it has matured. He decides to take a simple random sample of 10 corn plants. He labels the 100 plants 00-99. Refer to the given line from a random number table. Which numbers represent the sample of 10 corm plants? 58160 0969538399 40400 32662 46254 O 58, 16, 00, 96, 95, 38, 39, 94, 04, 00 O 58, 16, 00, 96, 95, 38, 39, 94, 04, 32 O 58, 16, 96, 95, 38, 39, 94, 04, 32, 66 58, 16, 09, 69, 38, 39, 40, 32, 66, 46
2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:
A worker wants to determine the average weight of fish fillets in his freezer. There are hundreds of boxes of fillets in the freezer with each box containing 15 fillets. He randomly selects 10 boxes of fish at random and pools all fillets in the 10 chosen boxes together as his sample. Is this simple random sampling, stratified sampling, or cluster sampling?
From a population of 300 you are going to select 50. Using the systematic sampling technique where 5 is the random start, what is the 4th sample unit?
The first unit of the sample is selected at random and then each subsequent unit is picked at a fixed from the previous unit selected in the sample. What sampling technique is this?
A principal at a large elementary school (grades 1 - 5) is considering making changes to the bus schedule. She selects a random sample of 100 students from each grade and contacts the students’ families regarding the bus schedule. What sampling technique is used in this example?
