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>

What’s the answer
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
FP * PH = GP * EP
If EP = 2, PG = 12, and FP = 4.
Then 4 * PH = 12 * 2
4 * PH = 12 * 2
step 1 simplify
4 * ph = 4PH
12 * 2 = 24
we now have 4PH = 24
step 2 divide each side by 4
4PH / 4 = PH
24 / 4 = 6
we're left with PH = 6
