ntted ar uter hardware ilure during the nited short circuits, WIII Ho DC TOlu and software. Past experience shows that the probability of failure first 1000 hours of operation for 16-kbit dynamic RAM producedbUt States firm is .2. It is hoped that new technology and stricte have reduced this failure rate. To verify this contention, 20 systems will monitored for 1000 hours and the number of failures will be recorded. (a) Set up the appropriate null and alternative hypotheses. (b) Explain in a practical sense the consequences of making a Type I and a 28. Quality and reliability are becoming important aspects of computer b durin r quality controls be Type II error.
