A certain change in a component part manufacturing process is considered. A sample of 1500 items was taken from the current process and 75 were found in poor condition. It is intended to incorporate a new process that claims that its percentage of defectives will be lower compared to the current process. The new process was implemented to make the comparison and 78 defectives were found in a sample of 2000. Since the implementation of the new process will entail a high investment in money, it will be selected only if the statement is proven to be valid.

Should the new process be implemented? Perform the pertinent calculations considering a confidence level of 98%. Answer this question using a confidence interval.
