SECTION 6.15 161 (c) Greater than 0.9. The power is greater than 0.9 against a difference of 3, so it will be greater than 0.9 against any difference greater than 3. Section 6.14 1. (a) There are six tests, so the Bonferroni-adjusted P-values are found by multiplying the original P-values by 6. For the setting whose original P-value is 0.002, the Bonferroni-adjusted P-value is therefore 0.012. Since this value is small, we can conclude that this setting reduces the proportion of defective parts. (b) The Bonferroni-adjusted P-value is 6(0.03) = 0.18. Since this value is not so small, we cannot conclude that this setting reduces the proportion of defective parts. 3. The original P-value must be 0 05 200 0025. 5. (a) No. Let X represent the number of times in 200 days that H0 is rejected. If the mean burn-out amperage is equal to 15 A every day, the probability of rejecting H0 is 0.05 each day, so X Bin 2000 05 . The probability of rejecting
