Answer:

140

Step-by-step explanation:

1 and 3 are vertical angles meaning they are equal. 4 and 3 make a straight angle. A straight angle is 180.

180-140=40

2 and 4 are straight angles so should be equal.

1=140

2=40

3=140

4=40

Answer: 0.418 < p < 0.512

Step-by-step explanation: A 95% conifdence interval for a population proportion is given by:

p + z\sqrt{\frac{p(1-p)}{n} }

where:

p is the proportion

z is score in z-table

n is sample size

The proportion for people who said "yes" is

p=\frac{202}{434} = 0.465

For a 95% confidence interval, z = 1.96.

Calculating

0.465 + 1.96*\sqrt{\frac{0.465(0.535)}{434} }

0.465 + 1.96*\sqrt{0.00057}

0.465 ± 1.96*0.024

0.465 ± 0.047

Interval is between:

0.465 - 0.047 = 0.418

0.465 + 0.047 = 0.512

<u>The interval with 95% of confidence is between 0.418 and 0.512.</u>
