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.
Half of the people bought tickets at $1.50, $1.50 times 15 equals $22.50
The other half bought them at the regular price of $2.75, $2.75 times 15 equals $41.25
When we combine the two money totals, we end up with a grand total of $63.75
If the range of the numbers in the list L is 4, then x can't be 4 since there is an element in the list that is x^2. Therefore,
0 ≤ x^2 ≤ 4 so that it would be the highest number and
0 ≤x ≤ 2
So, the value of x can be equal to 2 but not higher. So, 2 is always greater or equal to x.
