To apply the test of hypothesis and to compute the confidence level, P value, and the sample size lets vary the confidence level and the accuracy of the textbook example of the mean bonding strength of a lithium aluminum alloy (example 3 - 5, page 264} Remember that in the textbook example the: )5 =13.71 mega Pascal n was equal to 22 specimens. [1 = 0 05 TEA; = 21 = T002521: 1 2.030 S = 3.55 mega Pascal Assume u = 13 mega Pascal The accuracy is I} 1 mega Pascal, Questions: 1. It you change the alpha from [1.05 to an alpha of0.01 the critical T use in lhe hypothesis testing (from the table] is +2831? a. True b. False 2. The experimental T in the test of hypothesis is 0.938? a. True b. False 3 The null hypothesis is rejected? a. True b. False
