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
(a)Point Estimate for p,
(b)Point estimate for q, 1- (point estimate for p)
=1-0.3303
=0.6697
For this equation, you want to do it in fractions/ratios to properly solve it. You would have his average misses out of every field goal and his real missed attempts over total. It would look like this
= 
You want to solve for x since x is the total amount of field goals that he attempted. You can do this by doing cross multiplication:
(2)(x) = (8)(11)
From here you can get:
2x = 88
Divide each side by 2 to isolate x and you get:
x= 44
So he made a total of 44 field goals.
