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 ?

(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

(a)Point Estimate for p,

(b)Point estimate for q, 1- (point estimate for p)

=1-0.3303

=0.6697

B (a=60, b=120)

Step-by-step explanation:

1. m∠AOB = 180°

2. Since the ratio of a to b is 1:2, set the measure of a as x, and the measure of b as 2x.

3. a+b = 180, so x+2x = 180, 3x = 180, x = 60

4. x = a, so if x=60, then a = 60

5. if b=2x, then b = 2a, which is 2*60 = 120

Hope this helps
