- Race organizers want to survey the participating runners on the quality of the running course. Which of the following uses systematic random sampling? Select the first 15 finishers and the last 15 finishers to take the survey. Randomly select 15% of the male participants and 15% of the female participants. Select the 5th finisher (with the number 5 being randomly chosen) to survey, then survey every 15th finisher after that. Sort all of the runners' names alphabetically, then randomly choose 2 letters and survey all participants whose last name begins with one of those letters.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…What generally happens to the sampling error as the sample size is increased? O It gets smaller. O It gets larger. O It gets more predictable. O It gets less predictable.
- Can you help me identify the method of sampling used? (simple random, Systematic, Stratified, cluster, or convenience) A local school district contains 11 elementary schools. To obtain a sample of elementary school students, 4 of the 11 schools are randomly selected in all students in the selected schools are used in the sample.You need a sample of 40 students from your school. You use a random number table to pick 20 homerooms, then you use a random number table to pick 2 names from each homeroom list. What kind of sampling is this? stratified random sample convenience sampling o multi-stage sampling o simple random samplestic Identify the type of sampling used (random, systematic, convenience, stratified, or cluster sampling) in the situation described below. A woman is selected by a marketing company to participate in a paid focus group. The company says that the woman was selected because everyone in four randomly selected towns was being selected Which type of sampling did the marketing company use?
