To estimate the true proportion of adult citizens who are in favor of new gun control legislations, a random sample of 120 citizens yielded 50 who were in favor. what is an upper limit of a 90% confidence interval for the proportion of citizens who are in favor of the gun control legislation. enter your answer with two significant places after the decimal. (for example,0.1254 should be entered as 0.13)

0.49

Step-by-step explanation:

Given : To estimate the true proportion of adult citizens who are in favor of new gun control legislations, a random sample of 120 citizens yielded 50 who were in favor.

i.e. n=120

Sample proportion:

Critical value for 90% confidence=

Upper limit of Confidence interval for population proportion :

Hence,upper limit of a 90% confidence interval for the proportion of citizens who are in favor of the gun control legislation.= 0.49

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
