Automobile mechanics conduct diagnostic tests on 150 new cars of particular make and model to determine the extent 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. what is the margin of error for a 99% confidence interval based on these sample results? (round to four decimal places.) group of answer choices

0.0944

Step-by-step explanation:

Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.

Number of cars tested do have faulty catalytic converters =42

Then the proportion of cars   have faulty catalytic converters :

Critical value of z for 99% confidence level :

Formula for Margin of error :

Hence, the required margin of error =

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
