Answer:
[tex] n = 532[/tex]
And from the 532 adults in the sample we know that 174 adults said that they were not confident that the food they eat in country A is safe, and we can notate that with:
[tex] X= 174[/tex]
We can estimate the proportion of adults who said that they are not confident that the food they eat in country A is safe [tex]p_A[/tex] with this formula:
[tex]\hat p_A = \frac{X}{n}= \frac{174}{532}= 0.327[/tex]
And the complement rule is given by:
[tex] \hat q_A = 1- \hat p_A = 1-0.327= 0.673[/tex]
And this proportion represent the proportion of adults who NOT said that they are not confident that the food they eat in country A
Step-by-step explanation:
For this case we have the following info given from a survey.
The total sample size is 532 so then we have:
[tex] n = 532[/tex]
And from the 532 adults in the sample we know that 174 adults said that they were not confident that the food they eat in country A is safe, and we can notate that with:
[tex] X= 174[/tex]
We can estimate the proportion of adults who said that they are not confident that the food they eat in country A is safe [tex]p_A[/tex] with this formula:
[tex]\hat p_A = \frac{X}{n}= \frac{174}{532}= 0.327[/tex]
And the complement rule is given by:
[tex] \hat q_A = 1- \hat p_A = 1-0.327= 0.673[/tex]
And this proportion represent the proportion of adults who NOT said that they are not confident that the food they eat in country A
