Answer: 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:
<h2>n + 14 = 17</h2><h2>n = 3</h2>
Step-by-step explanation:
Sum of 14 and number means "n + 14" and equals 17 means "= 17."
Now that we have an equation, we can solve.
<h3>Step 1: Subtract 14</h3>
n = 3
<h3>Step 2: Check</h3>
3 + 14 = 17
17 = 17 ✔
