Complete Question

In 2015 as part of the General Social Survey, 1127 randomly selected American adults responded to this question: “Some countries are doing more to protect the environment than other countries. In general, do you think that America is doing more than enough, about the right amount, or too little?” Of the respondents, 514 replied that America is doing about the right amount. What is the 95 % confidence interval for the proportion of all American adults who feel that America is doing about the right amount to protect the environment.

The 95% confidence interval is    

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 1127

    The number that America is doing the about the right amount is k =  514

 Generally the sample proportion of the number that say america is doing about the right amount is mathematically represented as

=>          

=>          

From the question we are told the confidence level is  95% , hence the level of significance is    

=>  

Generally from the normal distribution table the critical value  of   is  

Generally the margin of error is mathematically represented as

=>  

=>  

Generally 95% confidence interval is mathematically represented as  

=>  

=>    

answer: two five pound bags one two pound

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
