Answer:
Following are the solution to this question:
Step-by-step explanation:
Just Parts (c) were discussed because they were mentioned in the issue.
A subpart of (c):
In point (i)
The answer is 1 for the CES since only CES has salary and wage rates information.
In point (ii)
The answer is 2 for the CPS because only the CPS has job status information.
In point (iii)
The answer is 3 for the CPS as detailed in this issue, neither CES nor CPS explicitly states gender information. Even so, population studies generally include a 'gender' requirement.
103 stays because it is the whole number and the next number after the decimal is below 5.
103 is your answer.
Since 50% are ripe, and you know that 25% are ripe apples, you also can assume 5% of apples aren’t ripe. From that you know that 50% + 5% is ripe oranges, and apples. So 45% are not ripe oranges
To get the probability of selecting a person who is a
democrat and is favour to the issue, let us first calculate for the portions in
each party who is favour on the issue.
p (rep & favour) = 0.4 * 0.3 = 0.12
p (dem & favour) = 0.6 * 0.7 = 0.42
Therefore the total portions who are favour is:
p (favour) = 0.12 + 0.42 = 0.54
Hence the probability is:
P (dem & favour) = 0.42 / 0.54 = 0.7778 = 0.78
Therefore there is about 78% probability that the person
selected who is favour to the issue is a democrat.
