Answer:
The claimed proportion (population) is
The sample proportion (p-hat) is
Step-by-step explanation:
In the population, we have the parameter p that is 11%.
Then, a sample of n=160 is taken and the proportion of the sample is 0.10.
The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.
FYI - 14,15,16 are correct.
17. a) 7 (nearest integer), b) 6.8 (nearest tenth)
18. a) 14 (nearest integer), b) 13.8 (nearest tenth)
19. --> simplified to = 2
