In order to draw inferences about the difference between two population proportions, , we take two independent samples − a sample of size from population 1 and a sample of size from population 2. Group of answer choices True False

For testing the difference between two population proportions, the pooled proportion estimate should be used to compute the value of the test statistic when the:Group of answer choicespopulations are normally distributed.sample sizes are large enough.null hypothesis states that the first population proportion is half of the second.null hypothesis states that the two population proportions are equal.

When testing the difference between two population proportions, a t test may be used.Group of answer choicesTrueFalse

Statistical Inference focuses on drawing conclusions about populations from samples?Group of answer choicesTrueFalse

Statistical inference ___ Group of answer choicesis the process of drawing inferences about the population based on the information taken from the sampleis the same as descriptive statisticsrefers to the process of drawing inferences about the sample based on the characteristics of the populationis the same as a census

A social scientist wishes to conduct a survey. She plans to ask a yes/no question to a random sample from the U.S. adult population. One proposal is to select 100 people; another proposal is to select 900 people.Which of the following is true regarding the sample proportion p̂ of "yes" responses? The sample proportion from the sample of 900 is more likely to be close to the true population proportion, p. The sample proportion from sample of 100 is more likely to be close to the true population proportion, p. The sample proportion in either proposal is equally likely to be close to the true population proportion, p, since the sampling is random.
