Let's examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 by drawing samples from these values, calculating the mean of each sample, and then considering the sampling distribution of the mean. To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…
Suppose you recruit the next 100 people who visit the DCC cafeteria to participate in a survey. One of the questions you ask is whether the student eats on campus (i.e., in the cafeteria) regularly, and you want to use the sample proportion to estimate the value of the (population) proportion of all DCC students who eat on campus regularly. Do you think this sampling method is likely to be biased? If so, in which direction? This sampling method is not likely to be biased and will produce a representative sample of DCC students. This sampling method is biased and is likely to yield an overestimate for the population proportion. This sampling method is biased and is likely to yield an underestimate for the population proportion.
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?
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?
A biologist wants to determine if different temperatures (15oC, 25oC, or 35oC) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations. What type of sampling is described in this study? one sample paired data two samples more than two samples
Question 4 Coach Smith wants to know whether students would pay for the privilege of parking their cars in the lot closest to the school. He surveyed students getting on the buses while he monitored bus loading each afternoon. What type of sampling technique is this? Your answer: O Simple random sampling O Stratified random sampling O Systematic sampling Cluster sampling Convenience sampling O o o O O
Identify which of these types of sampling is used: random, stratified, systematic, cluster, convenience. Professor Cuellar uses a computer to generate 20 random student ID numbers, then interviews the students corresponding to those numbers.
In which one of the following sampling techniques, the samples are selected based on the proportion of the categories? a. Stratified sampling b. Cluster sampling c. Systematic sampling d. Random Sampling
