In a sample of 400 voters, 360 indicated they favor the incumbent governor. the 95% confidence interval of voters not favoring the incumbent is 0.871 to 0.929

0.120 to 0.280

0.765 to 0.835

0.071 to 0.129

0.071 to 0.129

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.

In which

z is the zscore that has a pvalue of .

For this problem, we have that:

In a sample of 400 voters, 360 indicated they favor the incumbent governor. This means that 400-360 = 40 do not favor the incumbent governor. So

95% confidence interval

So , z is the value of Z that has a pvalue of , so .

The lower limit of this interval is:

The upper limit of this interval is:

The correct answer is:

0.071 to 0.129

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
