In non-probability sampling, the sample means can be used to estimate population means.

T or F

when developing a questionnaire, researchers should avoid:

		Spending too many resources
		Targeting busy areas
		Simple questions
		Making assumptions

If Don t-Know response is legitimate, it should be kept as a separate reply category.

T or F

Expert Solution

1 - False

In the non probability sampling , the odds of any member who is selected cannot be calculated . Hence the said statement is wrong

2 - Option D

Making assumptions

If the assumptions are made , it may not give proper space to the respondent to answer. The questions should be easy and meaningful , resources are not the matter of great concern. Hence option D will be correct

3 - True

If the answer of Dont know is a legitimate answer of the respondents , it should be included as a response in the questionaire as order to provide the extra comfort to the responsent. Not adding it may result in chaos.

1. T or F If a population is normally distributed, the sampling distribution of sample means will also always be normally distributed 2. If a population is not normally distributed when will the sampling distribution of sample means be guaranteed to have a normal distribution? 3. T or F For a given population and a given sample size there is only one sampling distribution of sample mean that will be generated. . 4. The following 2 terms are NOT exactly...

Which is false? A. A statistic is used to estimate an unknown parameter B. Non sampling errors can be present even when a census is taken C. Increase sample size to reduce bias D. Margin of error will get smaller when you increase sample size E. Variability describes how spread out the values of the sample statistic are when we take many samples.

The sample proportion p-bar provides an estimate for the population proportion p. The sampling distribution of the sample proportion is the probability distribution of the sample proportion. Consider a population with a proportion p = 0.60, from which a sample of size n = 200 is drawn. What is the sampling distribution of the sample proportion p-bar? Calculate the following probabilities using the distribution above: P(? < 0.5) P(? > 0.7) P(0.5 < ? < 0.7)

audit sampling, population, population unit, and sample

Define the following terms: audit sampling, population, population unit, and sample.

e) T F The larger the sample that is taken, the probability of making a type 2 error increases. f) T F We can never conclude that H0 is true based on taking a random sample from from the population. g) T F A stratified random sample is more preferred over a simple random sample when the population can be divided into homogeneous groups.

Distinguish between probability and non-probability sampling, discuss their types with examples.
