In 1996, the general social survey (which uses a method similar to simple random sampling) asked, "on the whole, do you think it should be the government's responsibility to provide decent housing for those who can't afford it?" for this question, 240 people said that it definitely should out of 1572 randomly selected people.
We will make a 90% confidence interval for standard error.

a) 0.1527
b) 0.0091
c) 0.000082
d) We need to know the confidence level to compute this.

b) 0.0091

Step-by-step explanation:

Hello!

The variable of interest is

X: Number of people that answered the social survey affirmatively out of 1572.

This variable has a binomial distribution.

The sample proportion is p'= 240/1572= 0.15

The distribution of the sample proportion (p') is

p'≈ N(p; )

The standard deviation of the distribution is

As you can see, the population proportion is present in the variance of the sampling distribution. To be able to estimate the population proportion using the sampling distribution, the variance must be estimated, so for the CI the standard error is

=

The correct answer is b)

I hope this helps!

answer: the answer is 23

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
