A private opinion poll is conducted for a politician to determine what proportion of the population favors adding more national

Ksju [112]

Answer:

n≅376

So sample size is 376.

Step-by-step explanation:

The formula we are going to use is:

$n=pq(\frac{z_{\alpha/2}}{E})^{2}$

where:

n is the sample size

p is the probability of favor

q is the probability of not in favor

E is the Margin of error

z is the distribution

α=1-0.98=0.02

α/2=0.01

From cumulative standard Normal Distribution

$z_{\alpha/2}=2.326$

p is taken 0.5 for least biased estimate, q=1-p=0.5

$n=0.5*0.5(\frac{2.326}{0.06})^{2}\\n=375.71$

n≅376

So sample size is 376

Equation for line passing through (4,3) perpendicular to y=5x+4

ehidna [41]

Perpendicular to the line y = 5x - 9

m= -1/5

the line passing through the point (1, 4):

4=-1/5*1+q
q= 21/5

the equation is:
y= -1/5x +21/5
or
x+5y-21=0
