You will use this tool to simulate taking random samples of 10 individuals from the U.S. voting-eligible population: 0 Set the Population Proportion to p = 0.67. - Set the Sample Size to \"n, = 10. - Simulate taking 1,000 random samples of size 10 by selecting "1,000" and clicking "Draw Sample(s)." The \"Sampling Distribution of Sample Proportion" graph at the bottom of the tool displays the distribution of the 1,000 sample proportions from your random samples. Use the \"Sampling Distribution of Sample Proportion" graph to approximate the proportion of the simulated samples with 0.6.

For a sample of 10 individuals from the U.S. voting-eligible population, the approximate probability that exactly individuals in the sample voted in the 2020 November presidential election is E Calculator Submit Question STAT_9B_Preview Score: 0/9 0/8 answered Question 6 The standard deviation of simulated sample proportions should be close to 0.15. Which of the following is a correct interpretation of this value? Hint The standard deviation of a variable is the amount by which we might expect a typical value of this variable to fall from its mean--the standard deviation from the mean. In this context, the variable is the sample proportion of individuals who voted in the 2020 November presidential election in a sample of size 10. . All sample proportions of individuals who voted in the 2020 November presidential election in random samples of size 10 will be 0.15 away from 0.67. O We would expect a typical sample proportion of individuals who voted in the 2020 November presidential election in a random sample of size 10 to be about 0.15 away from 0.67. O About 50% of sample proportions of individuals who voted in the 2020 November presidential election in random samples of size 10 will be between 0.52 and 0.82. We would expect a typical sample proportion of individuals who voted in the 2020 November presidential election to be around 0.15. Calculator Submit QuestionSTAT_9 B_Preview Score: 0/9 0/8 answered 0 Question 7 v Rather than using simulation, we can use mathematical theory to derive expressions for the mean and standard deviation of the sampling distribution of the sample proportion. Keep these properties in mind as you answer the remaining questions in this preview assignment. Sampling Distribution of the Sample Proportion When taking many random samples of size n from a population distribution with population proportion p: 0 The mean of the distribution of sample proportions is p. 0 The standard deviation of the distribution of sample proportions is Use a formula to calculate the standard deviation of sample proportions when taking random samples of size 10 from a population where 0.67. Round to four decimal places. Your answer should be close to the standard deviation of sample proportions in your simulation E Calculator Submit
