You may need to use the appropriate appendix table or technology to answer this question. The population proportion is 0.34. what is the probability that a sample proportion will be within 10.04 ofthe population proportion for each of the following sample sizes? (Round your answers to 4 decimal places.) (a) n = 100 |:| (b) n = 200 |:| (c) n = 500 |:| (d) n : 1,000 |:| (e) What is the advantage of a larger sample size? 0 There is a higher probability 5 will be within i0.04 of the population proportion p Q There is a higher probability a will be within i004 of the population standard deviation. p 0 As sample size increases, 5(5) approaches p. Q We can guarantee 3 will be within $0.04 of the population proportion p. Assume that the population proportion is 0.46. Compute the standard error of the proportion, OE, for sample sizes of 500,000, 1,000,000; 5,000,000; 10,000,000; and 100,000,000. (Round your answers to five decimal places.) sample size of 500,000 :| sample size of 1,000,000 :| sample size of 5,000,000 :| sample size of 10,000,000 :| sample size of 100,000,000 :I What can you say about the size of the standard error of the sample proportion as the sample size is increased? The standard error of the sample proportion, 0'5, and becomes extremely as the sample size becomes huge. INCREASEIDECREASE SMALLILARGE You may need to use the appropriate appendix table or technology to answer this question. After deducting grants based on need, the average cost to attend the University of Southern California (USC) is $27,175. Assume the population standard deviation is $7,400. Suppose that a random sample of 62 USC students will be taken from this population. {a} What is the value of the standard error of the mean? (Round your answer to the nearest whole number.) $|:| (b) What is the probability that the sample mean will be more than $27,175? |:| {c} What is the probability that the sample mean will be within $1,000 of the population mean? [Round your answer to four decimal places.) |:| (d) What is the probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100? [Round your answer to four decimal places.) |:| A sample of 5 months of sales data provided the following information. \"I...- m\".- {3} Develop a point estimate of the population mean number of units sold per month. |:| {b} Develop a point estimate of the population standard deviation. {Round vour answer to two decimal places.)
