35. Consider the Bernoulli case and Equation (14.11)

for continued sampling. Instead of the number of successes k, we can use the difference y  k  (n 

k)  2k  n between the number of successes and the number of failures.

a. Convert Equation (14.11) to express the bounds for continued sampling in terms of y.

b. Use part

(a) to express the bounds for continued sampling in Example 14.9 in terms of y.

c. Sketch the lines of part

(b) and also show y for the 23 observations. That is, redo Figure 14.4 in terms of y. Describe what happens to y as each new observation is included.
