Question

Let p be the population proportion for the following condition. Find the point estimates for p and q. In a survey of 1226 adults from country​ A, 405 said that they were not confident that the food they eat in country A is safe.
The point estimate for p, p^ is ?
The point estimate for q, q^ is ?

Answer 1

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
