Exercise 5.5

---

1. Give general expressions for the upper and lower one-sided N % confidence intervals for the differences in errors between two hypotheses tested on different samples of data.
   Hint: Modify the expression given in Section 5.5.
   
   

   Upper bound =	d_hat +
   	z( 100 - ( 2 * ( 100 - N ) ) ) *
   	square root [
   	error s1 ( h1 ) ( 1 - error s1 ( h1 ) ) / n1 +
   	error s2 ( h2 ) ( 1 - error s2 ( h2 ) ) / n2 ]
   Lower bound =	d_hat -
   	z( 100 - ( 2 * ( 100 - N ) ) ) *
   	square root [
   	error s1 ( h1 ) ( 1 - error s1 ( h1 ) ) / n1 +
   	error s2 ( h2 ) ( 1 - error s2 ( h2 ) ) / n2 ]
