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:
- Whites (includes Hispanic whites and other Caucasians)
- African Americans
- American Indian or Alaska Native
- Asian
- Native Hawaiian or Other Pacific Islander
- 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.
25 - (8-4) /6 *3 = 25 - 2 / 6 * 3
=25-1
=24 #
“/”= divide
“*”= multiply
Answer:
62.8, 63% if you around it off.
Step-by-step explanation: Do 49 Divided by 78, then times it by 100 to get your percentage. I just rounded it off to the nearest tenth and whole number just in case. Hope this helped!
Let the number be x
Equation:
12 + 5x = -3
Answer: The equation is 12 + 5x = -3
Solve it:
5x = -3 - 12
5x = -15
x = -15 ÷ 5
x = -3
Answer: The number is -3.
