Answer:
(a)0.3303
(b)0.6697
Step-by-step explanation:
Point estimation is the use of sample data to calculate a single value which serves as a best estimate of a given unknown population parameter.
Total Sample=1226
Number who said that they were not confident that the food they eat in country A is safe=405.
The point estimate of those who said that they were not confident that the food they eat in country A is safe is given as [TeX] \^{p}[/TeX]
(a)Point Estimate for p,
[TeX] \^{p}=\frac{405}{1226} =0.3303[/TeX]
(b)Point estimate for q, [TeX] \^{q}=[/TeX]1- (point estimate for p)
=1-0.3303
=0.6697
