Answer:

$y=3x-3$

Step-by-step explanation:

The equation of the line with the slope $m$ and passing through the point $(x_0,y_0)$ is

$y-y_0=m(x-x_0)$

In your case,

$m=3\\ \\x_0=3\\ \\y_0=6$

Hence, the equation of the line is

$y-6=3(x-3)\\ \\y-6=3x-9\\ \\y=3x-9+6\\ \\y=3x-3$

kykrilka [37]

Answer:

A. 0.4249

B. 95% CI = 0.4248-0.031 < p < 0.4249+0.030

C. 80% CI = 0.4249-0.0198 < p < 0.4249+0.0198

D.95% CI is wider than 80% CI.

The more confidence you want, the wider the CI must be.

Step-by-step explanation:

Poll asked for people's opinion on whether closing local newspapers would hurt civic life; 427 of 1005 respondents said it would hurt civic life a lot.

A.The proportion of the respondents who said closing local papers would hurt civic life a lot. (round to three decimal places as needed)

427/1005 = 0.4249

B. The 95% confidence interval for the population proportion who believed closing newspaper would hurt civic life a lot. Assume the poll used a simple random sample (SRS).

Therefore, 1.96√ 0.4249×0.57/1005 = 0.0304

95% CI 0.4248-0.031 < p < 0.4249+0.030

C. 80% confidence interval for the population proportion who believed closing newspapers would hurt civic life a lot.

= 1.2820×√[0.4249×0.57/1005] = 0.0198

80% CI: 0.4249-0.0198 < p < 0.4249+0.0198

D. 95% CI is wider than 80% CI.

The more confidence you want, the wider the CI must be.
