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 \^{p}

(a)Point Estimate for p,

\^{p}=\frac{405}{1226} =0.3303

(b)Point estimate for q, \^{q}=1- (point estimate for p)

=1-0.3303

=0.6697

3/4 of 80 is 60.
