You construct a sample in which Whites, Blacks, and Latinos are randomly selected from the U.S. adult population. The compositio

n of your final sample is 25% White, 30% Black, and 30% Latino. You've sampled from all over the country, but the actual composition of the population has a much higher proportion of Whites. This is likely an example of a:

Answer:

Stratified random sample error

Step-by-step explanation:

When you use stratified sampling, you divide the total population or universe  into strata (non-overlapping homogeneous groups). Then you draw a simple random sample (SRS) from each stratum (singular of strata).

You must make sure that your strata does not overlap, e.g. Latinos are not a race, but a culture and they come in all colors (whites, native indigenous, blacks, even Asians). That is why sometimes the term non-Hispanic whites is used.

Another reason why the sampling error might have occurred is that not all Caucasians are white, e.g. Arabs, people from northern Africa and most middle eastern Jews are considered Caucasians but their skin is tanned and it can be as dark as the skin of a Native American.

The US census only recognizes 5 races:

  1. Whites (includes Hispanic whites and other Caucasians)
  2. African Americans
  3. American Indian or Alaska Native
  4. Asian
  5. Native Hawaiian or Other Pacific Islander
  6. the sixth category is two or more races

As you can see, there is a lot of room for mistakes when you try to categorize people into races.

An Individual Retirement Account​ (IRA) has ​$17 comma 000in​ it, and the owner decides not to add any more money to the account
Umnica [9.8K]

Answer: The owner reaches at Rs. 56438.28 after 30 years.

Step-by-step explanation:

Since we have given that

Sum = Rs. 17000

Rate of compounded daily = 4%

Number of years = 30 years

So, Using "compound interest formula" we get that :

A=P(1+\dfrac{r}{n})^{nt}\\\\A=17000(1+\dfrac{0.04}{365})^{365\times 30}\\\\A=17000(1.000109589)^{10950}\\\\A=56438.28

Hence, The owner reaches at Rs. 56438.28 after 30 years.

Jorge gives an equal number of marbles to 6 friends. Which could be the total number of marbles he gave to his friends? (Answer
ladessa [460]

Answer:

D. 60

Step-by-step explanation:

Since the question stated that the number of marbles given out to his 6 friends were equal, we are certain that the total number of marbles is a factor or multiple of 6.

The only other assumption here is the number of marbles given has to be whole number. This means we just have to go through the answer choices and pick the one that is a multiple of 6.

A. 15 - This is wrong as 15 is not a multiple of 6.

B. 33 - This is wrong as 33 is not a multiple of 6.

C. 56 - This is wrong as 56 is not a multiple of 6.

D. 60 - This is CORRECT as 60 is a multiple of 6.

If Jorge gives each of his friends 10 marbles each, it would bring the total number of marbles to be 60.

FromTheMoon [43]
A) 20+10h

You know that you have 20 inches to start with, then it will grow 2h four times, or 8h total. Then it will grow h 2 times, or 2h. You add the 20, 8h, and 2h, to get 20+10h.

A fair spinner has 10 equal sections: 3 red, 3 blue and 4 green. It is spun twice. What is the probability of getting not green
Nonamiya [84]

Answer:

0.24

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.

Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green

= (3 + 3)/(3 + 3 + 4)

= 6/10

The probability of getting green

= 4/10

Hence the probability of getting not green then green

= 6/10 * 4/10

= 24/100

= 0.24
