Begin by subtracting 2500. 22600-2500=20100. Multiply 2500 by .4. 2500×.4=1000
Now, multilply the other number we found by .6. 20100×.6=12060. Add the two numbers, and the original 500 for Jason's gross pay for the month.
500+1000+12060=13,560

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.
