For a survey, one has a target population and a frame from which the sur- vey sample is drawn. Describe two ways a frame can differ from the target population. (c) A local Christchurch organisation wants to find out how people living in Christ- church feel about the Christchurch City Council’s performance. The organi- sation plans to collect responses by surveying people in the central city and several shopping malls throughout Christchurch. Describe the advantages and disadvantages of using this...

From each description, identify or infer the target population, the sampling frame, the unit of analysis, and the type of sample. Discuss whether the sampling strategy will allow the researcher to form inferences about the target population based on the sample. Problem: To study factors related to a diagnosis of depression in elderly individuals. Sample: A random selection of 150 of the 300 residents diagnosed with depression in one year while in a particular geriatric facility, and 340 randomly selected...

A sample that reflects the population accurately is called a Sampling Frame Population Representative Sample Sample Bias If generalization to population is needed, which sampling method should be used? Random Sampling Quota Sampling Convenience Sampling Purposive Sampling involves assigning numbers to answers so that they can be grouped into categories Sampling Recording Coding Editing

The list of individuals from which a sample is actually selected is called the sampling frame. Ideally, the sampling frame should list every individual in the population, but in practice this is often difficult. A sampling frame that leaves out part of the population is a common source of undercoverage. In the following questions select all choices that apply; to receive credit for the question you must select all the correct choices and only the correct choices. Question 1. A...

A sample of 44 observations is selected from one population with a population standard deviation of 3.1. The sample mean is 101.0. A sample of 56 observations is selected from a second population with a population standard deviation of 5.0. The sample mean is 99.5. Conduct the following test of hypothesis using the 0.10 significance level. H0:U1=U2 H1: U1 does not equal U2 a. is this a one or two tailed test? b.state the decision rule rounded 2 decimals the...

A sample of 65 observations is selected from one population with a population standard deviation of 0.75. The sample mean is 2.67. A sample of 50 observations is selected from a second population with a population standard deviation of 0.66. The sample mean is 2.59/ conduct the following test of hypothesis using the 0.08 significance level: Ho: m1 £ m2 H1: m1 > m2 Is this a one-tailed or a tow-tailed test? State the decision rule. Compute the value of...

A sample of 37 observations is selected from one population with a population standard deviation of 4.0. The sample mean is 100.5. A sample of 56 observations is selected from a second population with a population standard deviation of 4.4. The sample mean is 98.6. Conduct the following test of hypothesis using the 0.05 significance level. H0 : μ1 = μ2 H1 : μ1 ≠ μ2 Is this a one-tailed or a two-tailed test? One-tailed test Two-tailed test State the...

a sample of 245 observations is selected from a normal population for which the population standard deviation is known to be 25. the sample mean is 20. determine the standard error of the mean. determine the 90% confidence interval for the population mean.

A sample of 22 observations is selected from a normal population for which the population standard...

A sample of 22 observations is selected from a normal population for which the population standard deviation is known to be 8. The sample mean is 27. a. Determine the standard error of the mean. (Round the final answer to 3 decimal places.) The standard error of the mean is. b. Explain why we can use formula (8–1) to determine the 90% confidence interval, even though the sample size is less than 30. (Click to select) The population is normally distributed...
