der $100,000 per year. You are authorized to purchase 500 names chosen at random from 1 of the following 3 databases. Which database is most likely to fit your needs, and why? Income distribution Database 1 Database 2 Database 3 Mean $25,625 $49,205 $88,340 Standard deviation $15,990 $25,485 $35,870 Database 1, because its mean is farthest from the limit of $100,000 Database 1, because its standard deviation is smallest and so the data are most focused Database 2, because its mean is centered between $0 and $100,000 Database 3, because its mean is closest to $100,000 Database 3, because its standard deviation is largest

Answer:

Database 2, because its mean is centered between $0 and $100,000

Step-by-step explanation:

You desire the respondents to represent the full range of incomes under $100,000 per year. Then, database 2 is the one best fit this criteria, because is centered between $0 and $100,000, so there are more chances to select people from here which satisfy the desired criteria. In database 1 there are few people with salaries near $100,000, and in database 3  there are few people with salaries near $0

Two six-sided number cubes are rolled. Each number cube has sides numbered 1 through 6. What is the probability that the outcome
kvasek [131]
This is the concept of probability and statistics. Given that the cube has 6 sides, the probability space will be:
x={1,2,3,4,5,6,}
P(x)=1/6
When the two dice are tossed, the combination that will give us a sum that is multiple of 6 will be:
{1,2},{2,1},{1,1}
probability of obtaining this combination is:
(1/6*1/6)+(1/6*1/6)+(1/6*1/6)
=1/12
The combination that will give us a sum that is multiple of 4 is:
{1,1},{2,2}
Probability of obtaining this is:
(1/6*1/6)+(1/6*1/6)
=1/18
the probability that the sum will be a multiple of 6 or 4 will be:
1/12+1/18
=5/36
