- If a researcher uses random sampling, the sample will definitely be representative of the population. a) True b) FalseThe inferential procedures discussed in this book are intended for use with only one particular sampling procedure. What sampling procedure is that?#16) True or False Sampling error is the result of a mistake made during the sampling process
- When the Bureau of Labor Statistics conducts a survey, it begins by partitioning the United States adult population into 2,0072,007 groups called primary sampling units. Assume that these primary sampling units all contain the same number of adults. If you randomly select one adult from each primary sampling unit, is the result a simple random sample. Why or why not?30) Which among the following statement is true about the sampling method chosen here? a. This method is also known as judgement sampling b. It is a probability sampling method c. This method is based on the judgement of the researcher d. It is a non- probability sampling methodIn what is specific type of a sampling technique every 40th member of the population may particularly be selected?

Thank you.There is u very popular lottery in which a ticket is called a scratcher. In this lottery, 43% of the scratchers are winning ones. Suppose that we will take a random sample of 10 scratchers. Let p represent the proportion of winning scratchers from the sample. Consider the sampling distribution of the sample proportion p. Complete the following. Carry your intermediate computations to four or more decimal places. Write pur answers with two decimal places, rounding if needed.

- Let’s examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 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 a ten-sided die two times (or equivalently, roll two ten-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, 8, 9, and 10. The true mean (μ) of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 is , and the true standard deviation (σ) is . The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (10) times the number of possibilities on the second roll (also 10), or 10(10) = 100. If you collected all of these possible samples, the mean of your sampling distribution of means (μMM) would equal , and the standard deviation of your sampling distribution of means (that is, the…Suppose you implement double acceptance sampling with n1 = 100, c1 = 2, r = 5, n2 = 500, c2 = 5 and the true fraction nonconforming units is 0.02. Estimate the Average Sample Number.5. Which of the following is not a characteristic of stratified sampling? a) The researcher chooses who to approach and so might bias the sample 3 b) Those who are available to be surveyed in public places are unlikely to constitute a representative sample c) The random selection of units makes it possible to calculate the standard error. d) It is a relatively fast and cheap way of finding out about public opinions.
