In a past election, the voter turnout was 71%. in a survey, 1124 subjects were asked if they voted in the election. a. find the mean and standard deviation for the numbers of voters in groups of 1124. b. in the survey of 1124 people, 809 said that they voted in the election. is this result consistent with the turnout, or is this result unlikely to occur with a turnout of 71%? why or why not? c. based on these results, does it appear that accurate voting results can be obtained by asking voters how they acted?

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
