Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district. a poll

Nutka1998 [239]

Given that a particular candidate for public office is in fact favored by 48% of all registered voters in the district, thus p = 0.48

If a polling organization will take a random sample of 550 voters, i.e. n= 550.

The approximate probability that p̂ will be greater than 0.5 is given by:

$P(\hat{p}\ \textgreater \ 0.5)=1-P(\hat{p}\leq0.5) \\ \\ =1-P\left(z\leq \frac{0.5-0.48}{\sqrt{ \frac{0.48(1-0.48)}{550} }} \right) \\ \\ =1-P\left(z\leq \frac{0.02}{\sqrt{ \frac{0.2496}{550} }} \right)=1-P\left(z\leq \frac{0.02}{0.0213} \right) \\ \\ =1-P(z\leq0.9388)=1-0.82609=0.1739$

Therefore, the approximate probability that p̂ will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election is 0.1739.

I need help solving it please

MatroZZZ [7]

What you do here is replace is the given x value to find the y one

Like for the first box the y (top-to-down) would be found using y=3(-2)+4 which is gives y=-2

Applying the same for each in order:

(-2,-2)
(-1,0)
(0,4)
(1,7)
(2,10)

Ordered pairs are typed in (x,y) format like the answers I gave above
