Answer:
156.25% =P
Step-by-step explanation:
Is means equals and of means multiply
50 = P * 32
Divide each side by 32
50/32 = 32P/32
1.5625= P
Now we need to change it to percent form by multiplying by 100%
1.5625 * 100% = P
156.25% =P
Answer:
a) See answer below.
b) Equal chance of being selected.
c) Accuracy
Step-by-step explanation:
a. How might the strategy of leaving out cell phones affect the goal of obtaining a random sample of voters of consumers?
This strategy might affect the goal of obtaining a random sample by not choosing the sample from all the population of the USA. People who don't have a landline an only have a cell phone will have zero chance of being selected and therefore the polls will not be accurate.
b. Which criterion of random sampling is most likely to be violated by the problems you identified in part (a)?
Equal chance of being selected, since the people who only have cell phones will not be selected for the poll, this criterion of random sampling will be violated.
c. Which attribute of estimated consumer preference is most affected by the problem you identified in (a)
Accuracy. The definition of accuracy is how close a value really is to its true value.
By not selecting the sample from all the population, the results of the poll will likely be biased and therefore they might not be close to the actual preferences of consumers or voters.
