Step-by-step explanation:

Answer 2

The margin of error for the 90% confidence interval with a probability of success of 0.546 is 0.0183.

What is the margin of error?

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly.

Then the value of p will be

$\rm p = \dfrac{1092}{2000}\\\\p = 0.546$

And the z-value for the 90% confidence interval will be

$\rm z = 1.645$

And N = 2000

Then the margin of error (ME) will be

$ME = z \times \sqrt{\dfrac{p(1-p)}{N}}\\\\ME = 1.645\times \sqrt{\dfrac{0.546(1-0.546)}{2000}}\\\\ME = 0.0183$
