In a survey of 1,000 adults in a country, 652 said that they had eaten fast food at least once in the past month. Create a 95% confidence interval for the population proportion of adults who ate fast food at least once in the past month. Use a TI-83, TI-83 plus, or TI-84 calculator, rounding your answers to three decimal places.

95% confidence interval for the population proportion of adults who ate fast food at least once in the past month

( 0.6226  , 0.6814)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 1000

Given data in a survey of 1,000 adults in a country, 652 said that they had eaten fast food at least once in the past month

Sample proportion

Step(ii):-

95% confidence interval for the population proportion of adults who ate fast food at least once in the past month

( 0.652 -   0.0294 ,0.652 + 0.0294 )

( 0.6226  , 0.6814)

Final -

95% confidence interval for the population proportion of adults who ate fast food at least once in the past month

( 0.6226  , 0.6814)
