<u>Check One Sample Z-Interval Conditions</u>
Simple Random Sample? √
np≥10? √
n(1-p)≥10? √
<u>One-Sample Z-Interval Information</u>
- Formula -->
- Sample Proportion -->
- Critical Value -->
(for a 85% confidence level)
- Sample Size -->
- Margin of Error (MOE) -->
<u>Problem 1</u>
As stated previously, Anas should use the critical value to construct the 85% confidence interval
<u>Problem 2</u>
Given our formula for the margin of error (MOE), the value is
<u>Problem 3</u>
The 85% confidence interval would be , which means that we are 85% confident that the true proportion of people that clicked on the advertisement is between 0.1786 (~45 people) and 0.2534 (~63 people)
<u>Problem 4</u>
Increasing the sample size to is going to decrease the margin of error because it is a closer representation of the population, but, alas, requires more time, energy, and resources to observe.
Answer:
Step-by-step explanation:
The complete question in the attached figure
we know that
When two lines are crossed by another line (transversal), a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal, are called <em><u>Alternate Interior Angles</u></em>.
When the two lines being crossed are Parallel Lines the Alternate Interior Angles are congruent
In this problem
---> by alternate interior angles
we have
therefore
