The situation is the same as described in Prob. 7.6- 1 except that Wyndor management does not consider the additional information about the rumor to be reliable. Therefore, they havenít yet decided whether their best estimate of the probability that the rumor is true should be 0.5 or 0.75 or something in between. Consequently, they have asked you to find the break-even point for this probability below which the optimal plan presented in Sec. 7.6 will no longer be optimal. Use trial and error to find this break-even point (rounded up to two decimal points). What is the new optimal plan if the probability is a little less than this break-even point?
