Answer:
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:
We can estimate the proportion of adults who said that they are not confident that the food they eat in country A is safe with this formula:
And the complement rule is given by:
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:

Answer:
v = ±
Step-by-step explanation:
Given
v² = 47 ( take the square root of both sides )
v = ± ← note plus or minus
Since × = 47
and
- × - = 47
0.02/ zero point zero two
Evaluate
where
and
f(5) = 5 - 4 = 1
g(1) = 3 * 1 + 6 = 3 + 6 = 9
f(6) = 6 - 4 = 2
g(-2) = 3 * (-2) + 6 = -6 + 6 = 0
So,
I hope this helps. =)
