Rajesh calculated 95% confidence level. What does he mean by that? (A) He can be 95% confident that his sample will include the population parameter. Choose the correct answer from the options given below: |
(A) and (C) only (B) and (C) only (D) only (A) and (B) only |
(A) and (C) only |
The correct answer is Option (1) → (A) and (C) only $\text{A 95% confidence level means that in repeated sampling,}$ $\text{about }95\%\text{ of the confidence intervals constructed will contain the true population parameter.}$ $\text{Hence there is }5\%\text{ probability that the interval will not contain the parameter.}$ $(A)\;\text{True.}$ $\text{Sample interval includes the population parameter with }95\%\text{ confidence.}$ $(C)\;\text{True.}$ $\text{Equivalently, there is }5\%\text{ chance that it does not include the parameter.}$ $(B)\;\text{False.}$ $(D)\;\text{False.}$ $\text{Correct statements: (A) and (C).}$ |
