I Question 8 5 pts A survey research company uses random digit dialing. They have a contract, to estimate the percentage of people watching Spanish-language television in several Southwestern cities. They took a sample of size 1,000 in Austin, Texaswhich has about 600,000 residents. They are satised with the accuracy of the estimates for Austin. Dallas has about twice the population of Austin, but similar demographics. To get about the same accuracy in Dallas as in Austin, what should the sample size the company take from Dallas, assuming that they would use exactly the same sampling process? 0 Need more information. 0 2,000 g 1,000 O 500 0 4,000 D Question 9 6 pts Twenty-ve draws are made at random with replacement from the box of 4 tickets: "1", "1", "2", "4". Matching the following graphs with descriptions. [ Choose ] The probability histogram for the average of 20 draws J The histogram for the numbers in the 20 draws The histogram for the numbers in the box The histogram for the numb: V The probability histogram f0| V Question 10 14 pts Five hundred draws are made at random with replacement from a box with 10,000 tickets. The average of the box is unknown. However, the average of the draws was 71.3, and their SD was about 2.3. Decide each of the following statement is true or false. I. The average of the box is likely to be around 71.3, and the SD of the box is likely to be around 2.3 II. The SE computed by 27330 N 0.1 says that this number 2.3 is likely to be off by 0.1 or so. Ill. The SE computed by zg N 0.1 says that this number 71.3 is likely to be off by 0.1 or so. IV. A 68%-condence interval is for the average of box is 71.3 i 0.1. V. The chance for the actual average of box to be within the range 71.3 i 0.1 is about 68%. VI. About 68% of tickets in the box are within the range of 71.3 i 0.]. VII. About 68% of tickets in the box are within the range of 71.3 i 2.3
