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:
SWEEEET!!
Step-by-step explanation:
:D
Tangent is the ratio opposite/adjacent
tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer
The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
Answer:
C = 31
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
