8. 2 distribution of the sample proportion learning objectives: describe the sampling distribution of a sample proportion 2. 8. 2. 1 describe the sampling distribution of a sample proportion (1 of 11) Suppose that a random sample of size n is obtained from a population in which each individual either does or does not have a certain characteristic. 8. 2. 1 describe the sampling distribution of a sample proportion (2 of 11) In a quinnipiac university poll conducted in may of 2008, 1745 registered voters nationwide were asked whether they approved of the way george w. bush is handling the economy. Obtain a point estimate for the proportion of registered voters who approve of the way george w. bush is handling the economy. 8. 2. 1 describe the sampling distribution of a sample proportion (3 of 11) Parallel example 2: using simulation to describe the distribution of the sample proportion. Describe the sampling distribution of the sample proportion for samples of size n = 10, 50, 100.
