(3.83% , 8.69%)
95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices
(0.406 , 0.454)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given random sample size 'n' = 369
Sample proportion
95% confidence intervals are determined by
(0.0623 - 0.0246 , 0.0623 + 0.0246)
(0.0383 , 0.0869)
(3.83% , 8.69%)

(3.83% , 8.69%)
<u>Step(ii):-</u>
Given 43% of those polled blamed of companies the most for the recent increase in gasoline prices
sample proportion 'p' = 0.43
Given Margin of error (M.E) = 0.024
95% confidence intervals are determined by
(0.406 , 0.454)
<u>Final answer</u>:-
95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices
