. A new rocket-launching system is being considered for deployment of small, short-range rockets. A sample of 80 experimental launches is made with the new system, and 54 are successful. (a) Create a 98% confidence interval for the proportion of successful launches for the new rocketlaunching system.

(b) The existing system has p = 0.69 as the probability of a successful launch. Would you conclude that the new system is better than the existing system? Why or why not?
