Which choice best describes a simple random sample? O a selection of members of a population chosen because of their convenient accessibility and proximity O when a population is first sorted into groups that share a similar characteristic and individuals are randomly chosen from each of the groups O a selection of members from a population in such a way that every possible sample of the same size has an equal chance of being chosen O when a population is...

(1 point) For each problem, select the best response. (a) A simple random sample of size n is defined to be A. a sample of size n chosen in such a way that every unit in the population has the same chance of being selected. B. a sample of size n chosen in such a way that every set of n units in the population has an equal chance to be the sample actually selected. C. a sample of size...

1 point) For each problem, select the best response. (a) A simple random sample of size n is defined to be A. a sample of size n chosen in such a way that every unit in the population has a known nonzero chance of being selected. B. a sample of size n chosen in such a way that every unit in the population has the same chance of being selected. C. a sample of size n chosen in such a...

Identify which type of sampling is used: random, stratified, cluster, convenience, voluntary response, or systematic. 1. A local business man attends a community event highlighting local businesses and asks attendees how they feel about one of his new products. 2. A large company drug tests its employees once a month. It is too expensive to test all the employees so the company assigns a number to each employee and has a computer randomly generate 15 numbers each month. The numbers...

3. Determine which sampling (simple random, stratified, cluster, systematic, or convenience) is used in the following situation: a. If we have a population of 100 elements and we want a sample of 50 elements, first of all, we establish the selection interval that will be equal to 5. If we choose the first element, randomly taking a number between 1 and 5, and, at from it we obtain the remaining elements of the sample. 8. Identify if the following situation...

The serum cholesterol levels of a population of 12-14 year olds follow a normal distribution with a mean of 162 mg/dl and a standard deviation of 28 mg/dl. Consider randomly selecting 9 individuals of this population, measuring each individual's cholesterol level, and then computing the sample mean of these 9 subjects 3. 1 pt If X is the sample mean cholesterol level of the 9...

CLUSTER SAMPLING WITH ESTIMATION Suppose a population of size N is divided into K- N/M groups of size M. We select a sample of size n -km the following way: » First we select k groups out of K groups by simple random sampling . We then select m units in each group selected on the first step by simple random sampling . The estimate of the population mean is the average Y of the sample. Let μί be the...
