Given:
p = 20% = 0.2, sample proportion
n = 5000, sample size.
Confidence level = 95%
The confidence interval is
(p - 1.96k, p + 1.96k)
where
Therefore the 95% confidence interval is
(0.1943, 0.2057) = (19.4%, 20.6%)
Answer: The 95% confidence interval is (19.4%, 20.6%)

Answer:
The value of m is .
Step-by-step explanation:
If two vectors and
are perpendicular to each other then their dot product will be zero i.e
If two vectors and
are parallel to each other then their cross product will be zero i.e
Given vectors are a= (3,4) and b=(m,2)
The position vector of is =
The position vector of is =
Since and
are perpendicular.
Then,
⇒3.m +4.2=0
⇒3m+8=0
⇒3m= -8
The value of m is .
