Answer:
The margin of error for a 90% confidence interval is 0.075.
Step-by-step explanation:
We are given that he asks listeners to phone in and vote "yes" if they agree the drinking age should be lowered and "no" if not.
Of the 100 people who phoned in, 70 answered "yes."
Let = sample proportion of people who say yes
So, =
= 0.70
where, X = Number of people who say yes = 70
n = Number of people phoned in = 100
<u>Now, Margin of error formula for any confidence interval is given by;</u>
Margin of error =
where, = level of significance = 10%
Standard of error =
Also, the critical value of x at 5% () level of significance is 1.645.
SO,<em><u> Margin of Error</u></em> =
=
= 0.075
Hence, the margin of error for a 90% confidence interval is 0.075.
1. We can conclude that the result of the division is 
with a remainder of 
, or in other notation: 
. Check the steps in the first image.
3. We can conclude that the result of the division is
with a remainder of 2, or in other notation: 
. Check the steps in the firts image.
5. We can conclude that the result of the division is
with a remainder of 5, or in other notation: 
. Check the steps in the first image.
7. To check if
is a factor of 
, we are going to perform long division. If the result of the long division has no remainder, is a factor of .
Since the result of the long division has no remainder, we can conclude that is a factor of . Check the steps in the second image.
