Paint QR Code In None Using Barcode encoder for Software Control to generate, create QR Code image in Software applications. (b) For a twotailed test at a 0.01 level of significance, we adopt the decision rule: (1) Accept H0 if T lies inside the interval interval 3.25 to 3.25. (2) Reject H0 otherwise. Since T 3.00, we accept H0 at the 0.01 level. Because we can reject H0 at the 0.05 level but not at the 0.01 level, we can say that the sample result is probably significant (see terminology at the end of Problem 7.5). It would therefore be advisable to check the machine or at least to take another sample. (c) The P value is P(T 3) P(T 3). The table in Appendix D shows that 0.01 computer software, we find P 0.015.

A test of the breaking strengths of 6 ropes manufactured by a company showed a mean breaking strength of 7750 lb and a standard deviation of 145 lb, whereas the manufacturer claimed a mean breaking strength of 8000 lb.

Making Data Matrix 2d Barcode In None Using Barcode printer for Software Control to generate, create Data Matrix image in Software applications. (a) For a onetailed test at a 0.05 level of significance, we adopt the decision rule: (1) Accept H0 if T is greater than (2) Reject H0 otherwise. Since T 3.86, we reject H0. t0.95, which for 6 1 5 degrees of freedom means T 2.01. Encode USD8 In None Using Barcode drawer for Software Control to generate, create Code 11 image in Software applications. Paint Bar Code In Visual Studio .NET Using Barcode drawer for ASP.NET Control to generate, create barcode image in ASP.NET applications. (b) For a onetailed test at a 0.01 level of significance, we adopt the decision rule: (1) Accept H0 if T is greater than (2) Reject H0 otherwise. Since T 3.86, we reject H0. We conclude that it is extremely unlikely that the manufacturer s claim is justified. (c) The P value is P(T P 0.006. 3.86). The table in Appendix D shows 0.005 P 0.01. By computer software, t0.99, which for 5 degrees of freedom means T 3.36.

Reading UPC A In Visual C# Using Barcode decoder for VS .NET Control to read, scan read, scan image in Visual Studio .NET applications. 7.18. The IQs (intelligence quotients) of 16 students from one area of a city showed a mean of 107 with a standard deviation of 10, while the IQs of 14 students from another area of the city showed a mean of 112 with a standard deviation of 8. Is there a significant difference between the IQs of the two groups at a (a) 0.01, (b) 0.05 level of significance (c) What is the P value of the test Code39 Generator In .NET Framework Using Barcode encoder for ASP.NET Control to generate, create Code 39 image in ASP.NET applications. Code 3/9 Encoder In ObjectiveC Using Barcode creator for iPad Control to generate, create Code 3/9 image in iPad applications. If m1 and m2 denote population mean IQs of students from the two areas, we have to decide between the hypotheses H0: m1 m2, and there is essentially no difference between the groups H1: m1 2 m2, and there is a significant difference between the groups Under the hypothesis H0, T # X1 s 21>n1 # X2 1>n2 where s n1S2 n2S2 1 2 A n1 n2 2 Then s 16(10)2 14(8)2 A 16 14 2 9.44 and T 112 9.44 21>16 107 1>14 1.45
(a) On the basis of a twotailed test at a 0.01 level of significance, we would reject H0 if T were outside the range t0.995 to t0.995, which, for n1 n2 2 16 14 2 28 degrees of freedom, is the range 2.76 to 2.76. Therefore, we cannot reject H0 at a 0.01 level of significance. (b) On the basis of a twotailed rest at a 0.05 level of significance, we would reject H0 if T were outside the range t0.975 to t0.975, which for 28 degrees of freedom is the range 2.05 to 2.05. Therefore, we cannot reject H0 at a 0.05 level of significance. We conclude that there is no significant difference between the IQs of the two groups. (c) The P value is P(T 1.45) software, P 0.158. P(T 1.45). The table in Appendix D shows 0.1 P 0.2. By computer 7.19. At an agricultural station it was desired to test the effect of a given fertilizer on wheat production. To accomplish this, 24 plots of land having equal areas were chosen; half of these were treated with the fertilizer and the other half were untreated (control group). Otherwise the conditions were the same. The mean yield of wheat on the untreated plots was 4.8 bushels with a standard deviation of 0.40 bushels, while the mean yield on the treated plots was 5.1 bushels with a standard deviation of 0.36 bushels. Can we conclude that there is a significant improvement in wheat production because of the fertilizer if a significance level of (a) 1%, (b) 5% is used (c) What is the P value of the test If m1 and m2 denote population mean yields of wheat on treated and untreated land, respectively, we have to decide between the hypotheses H0: m1 H1: m1 Under the hypothesis H0, T Then s 12(0.40)2 12(0.36)2 12 12 2 A 0.397 and T 5.1 4.8 0.397 !1>12 1>12 1.85 # X1 s !1>n1 # X2 1>n2 where s n1S2 n2S2 1 2 A n1 n2 2 m2, and the difference is due to chance m2, and the fertilizer improves the yield
