Answer:
Step-by-step explanation:
a. Systematic sampling
Reason-Every individual will be in the sample. The is referred to as the sampling interval.
-The sampling interval has a random start point but with a fixed, periodic interval.
-This method was appropriate given the homogeneous nature of the population.
-It is also representative given it has no bias.
b. A sample frame is the part of a population from which information is drawn.# In our sample, the sample frame is person.
#No parts c, d as implied in the question
Answer:
Step-by-step explanation:
The line integral is
Now evaluate the integrals separately
therefore
Answer:
(3)3 - 21/3 + 6 --> 9 - 27/3 --> -18/3
Answer: x + 6
Step-by-step explanation:
We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.
Given:
2(3/5x+3)
Distribute:
2 * (3/5x) + (2 * 3)
6/5x + 6
Answer:
x + 6
Answer:
Data skewed to the right is usually a result of a lower boundary in a data set (whereas data skewed to the left is a result of a higher boundary). So if the data set's lower bounds are extremely low relative to the rest of the data, this will cause the data to skew right. Another cause of skewness is start-up effects.
