ducational Television In a random sample of people, said that they watched educational television. Find the confidence interval

SIZIF [17.4K]

Complete Question

Educational Television In a random sample of 200 people, 159 said that they watched educational television. Find the 90% confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.

Answer:

The 90% confidence interval is $0.748 < p < 0.842$

Step-by-step explanation:

From the question we are told that

The sample size is n = 200

The number of people that watched the educational television is $k = 159$

Generally the sample proportion is mathematically represented as

$\^ p = \frac{159}{200}$

=> $\^ p = 0.795$

From the question we are told the confidence level is 90% , hence the level of significance is

$\alpha = (100 - 90) \%$

=> $\alpha = 0.10$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.645$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} }$

=> $E = 1.645 * \sqrt{\frac{0.795 (1- 0.795)}{200} }$

=> $E = 0.04696$

Generally 95% confidence interval is mathematically represented as

$\^ p -E < p < \^ p +E$

=> $0.795 -0.04696 < p < 0.795 + 0.04696$

=> $0.748 < p < 0.842$

At what point do the lines y= 2x + 3 and y = 5x - 9 intersect?

QveST [7]

Answer:

(4,11)

Step-by-step explanation:

y=2x+3

y=5x-9

the first equation is equal to the second equation so

2x+3=5x-9

put like terms together

2x-5x= -9-3

-3x= -12

divide both sides by -3

.•.x=4

now, use the value of x to find the value of y like this:

y=2x+3 (x=4)

y=2(4)+3

y=8+3

y=11

therefore, the two lines intersect at the point (4,11)
