This question is asking only for the slope of the regression equation. This slope can be easily calculated using the following rule:
slope = SP / SSx
Examining the givens, we will find that both parameters are given where:
SP = 30 and SSx = 10
Substituting with the givens in the above mentioned equations, we can calculate the slope as follows:
slope = 30 / 10 = 3
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
9/16 = 0.5625
Rounded Equals 0.5630
