Answer:
The 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Step-by-step explanation:
The complete question is:
A random sample of 1014 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?" Of the 1014 adults surveyed, 538 indicated that televisions are a luxury they could do without.Construct and interpret a 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without.
Solution:
In a sample of 1014 adults, 538 indicated that televisions are a luxury they could do without.
Compute the sample proportion of adults who indicated that televisions are a luxury they could do without as follows:
The (1 - <em>α</em>)% confidence interval for population proportion is:
The critical value of <em>z</em> for 95% confidence interval is:
*use a <em>z</em>-table.
Compute the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without as follows:
Thus, the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Answer:
4.35 - 3.25= 1.1
A = 1.1
Step-by-step explanation:
I do understand but someone probably already answered it. Because that’s geometry easy
Answer:
if you are solving for X
Step-by-step explanation:
first you do a thing i call jump multiplying
so like 5x2X+ 5x4
then you do basic maths
10X=20
X=2
-13,4, - 9/2 is the answer :)
