In point estimation a. data from the population is used to estimate the population parameter b. data from the sample is used to

icang [17]

Answer:

Option B) data from the sample is used to estimate the population parameter

Step-by-step explanation:

Point estimation:

Its is the process of getting a point estimate from a sample that describes a population parameter in the best way.
We calculate the unknown population parameter with the help of a sample drawn from the population.
It is similar to interval estimation.
In interval estimation we obtain an interval in which the population parameter may lie but in point estimation we obtain a single value which is the best approximation of population parameter.

Thus, the correct answer is

Option B) data from the sample is used to estimate the population parameter

Simplify and then evaluate the equation when a= 2 and b = 4. b2 + 3(b – 62) – 2a= [?]

I am Lyosha [343]

Answer:

-170

Step-by-step explanation:

First, you would substitute 2 and 4 for a and b. 4 times 2 + 3(4 - 62) - 2 times 2 = ?

Then, do 4 times 2 (8), 3(4-62)=3(-58)

8 + -174 - 4 = -170

What function equation is represented by the graph?

kupik [55]

the answer would be ...

f(x) = -5/2x + 4

We know this because the constant in this equation, 4, is the y-intercept!

This means that the number without the variable is where the line intersects the y-axis.

Additionally, the slope is called the "rise over run", but in this case it is negative. At the point, 4, on the y-axis, we go down 5 units (the numerator of the slope) and to the right by 2 units (the denominator).

We find ourselves at where the line intercepts the x-axis!

I hope my explanation isn't confusing and that it is helpful! If you have any questions or concerns, message me! :)
