Answer: 0.418 < p < 0.512
Step-by-step explanation: A 95% conifdence interval for a population proportion is given by:

where:
p is the proportion
z is score in z-table
n is sample size
The proportion for people who said "yes" is
= 0.465
For a 95% confidence interval, z = 1.96.
Calculating


0.465 ± 1.96*0.024
0.465 ± 0.047
Interval is between:
0.465 - 0.047 = 0.418
0.465 + 0.047 = 0.512
<u>The interval with 95% of confidence is between 0.418 and 0.512.</u>
Answer: X = 1
Step-by-step explanation:
3 x
+ 4 + 1 =
+ 4
First, you would want to cancel out the equal terms, in this case its the +4's
3 x
+ 1 =
I would also change the
into a 1
3 x 1 +1 =
Now multiply and add
3 + 1 =
4 =
divide both sides by 4
x = 1
