(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 Bonferroniadjusted
P
values are found by multiplying the original
P
values by 6.
For the setting whose original
P
value is 0.002, the Bonferroniadjusted
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 Bonferroniadjusted
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.
