Automobile mechanics conduct diagnostic tests on 150 new cars of particular make and model, to determine the extend to which they are affected by a recent recall due to faulty catalytic converters. They find that 42 of the new cars tested do have faulty catalytic converters. e. Automobile mechanics want the estimate for the true proportion of new cars with faulty catalytic converters to be within 0.01 with 95% confidence, how many new cars should they sample?
