(a) Work Problem 6.11 assuming that the methods of large sampling theory are valid. (b) Compare the results of the two methods. Create QR Code JIS X 0510 In VS .NET Using Barcode generation for ASP.NET Control to generate, create QR Code ISO/IEC18004 image in ASP.NET applications. Make QR Code In VS .NET Using Barcode generator for .NET Control to generate, create QR Code image in .NET framework applications. (a) Using large sampling theory, the 95% confidence limits are # X 1.96 s !n 4.38 1.96 0.06 !10 4.38 0.037 inch Print QRCode In VB.NET Using Barcode printer for .NET framework Control to generate, create QR Code 2d barcode image in Visual Studio .NET applications. Code 39 Drawer In None Using Barcode printer for Software Control to generate, create Code 3 of 9 image in Software applications. where we have used the sample standard deviation 0.06 as estimate of s. Similarly, the 99% confidence limits are 4.38 (2.58)(0.06)> !10 4.38 0.049 inch. (b) In each case the confidence intervals using the small or exact sampling methods are wider than those obtained by using large sampling methods. This is to be expected since less precision is available with small samples than with large samples.

Creating Barcode In Java Using Barcode generation for Android Control to generate, create barcode image in Android applications. (c) The 99.73% confidence limits for p are 0.55
For a more exact method of working this problem, see Problem 6.27.
6.14. How large a sample of voters should we take in Problem 6.13 in order to be 95% confident that the candidate will be elected The candidate is elected if p 0.50, and to be 95% confident of his being elected, we require that Prob. ( p 0.50) 0.95. Since (P p)> !p(1 p)>n is asymptotically normal, Prob. P !p(1 p p)>n b b 1 3 `e !2p u2>2 du
Prob. ( p
0.50) P
b!p(1 p)>n) b 1 3 `e !2p
u2>2 du
Comparison with Prob.( p
0.95, using Appendix C, shows that b !p(1 p)>n 0.50 where b 1.645
Then, using P
0.55 and the estimate p 0.55
0.55 from Problem 6.13, we have 0.50 or n 271
1.645!(0.55)(0.45)>n
6.15. In 40 tosses of a coin, 24 heads were obtained. Find (a) 95%, (b) 99.73% confidence limits for the proportion of heads that would be obtained in an unlimited number of tosses of the coin. (a) At the 95% level, zc 1.96. Substituting the values P 24 > 40 0.6 and n 40 in the formula p P zc !P(1 P)>n, we find p 0.60 0.15, yielding the interval 0.45 to 0.75. (b) At the 99.73% level, zc 3. Using the formula p yielding the interval 0.37 to 0.83. P zc !P(1 P)>n, we find p 0.60 0.23, The more exact formula of Problem 6.27 gives the 95% confidence interval as 0.45 to 0.74 and the 99.73% confidence interval as 0.37 to 0.79. Confidence intervals for differences and sums 6.16. A sample of 150 brand A light bulbs showed a mean lifetime of 1400 hours and a standard deviation of 120 hours. A sample of 200 brand B light bulbs showed a mean lifetime of 1200 hours and a standard deviation of 80 hours. Find (a) 95%, (b) 99% confidence limits for the difference of the mean lifetimes of the populations of brands A and B. Confidence limits for the difference in means of brands A and B are given by # XA (a) The 95% confidence limits are 1400 # XB 1200 zc s2 A A nA s2 B nB (80)2 >100 200 24.8. 1.96 !(120)2 >150
Therefore, we can be 95% confident that the difference of population means lies between 175 and 225 hours. (b) The 99% confidence limits are 1400 1200 2.58 !(120)2 >150 (80)2 >100 200 32.6. Therefore, we can be 99% confident that the difference of population means lies between 167 and 233 hours. 6.17. In a random sample of 400 adults and 600 teenagers who watched a certain television program, 100 adults and 300 teenagers indicated that they liked it. Construct (a) 95%, (b) 99% confidence limits for the difference in proportions of all adults and all teenagers who watched the program and liked it.
