1. (True or False)A sample of union memebers were selected and their opinions regarding the proposed management union contract were recorded with 1600 out of the 2000 members in favor of it. Using the 0.95 degree of confidence the interval estimate for the population proportion was computed to be 0.78 and 0.82. This indicated that about 68 out of 100 similarly constructed intervals would include the population proportion.2. (True or False) In a nonproportional stratified the sample, the number of items studied in each stratum is disproportionate to their number in the popluation. We then weight the sample results according to the stratum’s proportion of the total population.3. (true or False)The Central Limit Theorem states that the sampling distribution of the sample means of all possible samples of sizes n generated from any population will be approximate normally distribution.4. (True or False) the standard error of the mean will vary according to the size of the sampke that is the denominator. As the sample size n gets larger and larger, the variability of the sample means gets smaller and smaller.5.(True or False) One factor in determining the size of a sample is the degree of confidence selected. This is usually 0.95 or 0.99, but it may be any degree of confidence you specify.6. (true or False) in order to determine the size of a sample, the standard deviation of the population must be estimated. to do this, we can either take a pilot survey or it can be approximated based on a knowledge of the population.7. (true or False) the variation in the population as measured by the standard deviation has little or no effect in determining the size of a sample selected from the population.”
