According to a recent study, only 41% of auto mechanics correctly diagnose a common vehicle problem. Nine auto mechanics are randomly selected and then each is tested to see if she/he correctly diagnoses the vehicle problem. Use this situation to answer the parts below. (a) Recognizing that this is a binomial situation, give the meaning S and F in this context. That is, define what you will classify as a "success" and what you will classify as a "failure" when one adult is...

4. At a local hospital, babies are born at an average rate of four births per night (consider "night" to be an 8 hour period from 10pm to 6am). Assume that the time that elapsed from one birth to the next has the exponential distribution. Take note that we are concerned only with the rate at which babies are born, and we are ignoring the time spent in labor. We must also assume that the times spent between births are...
