Answer 1

Dear student please Thumbs Up... Thanks..

3)

Answer: True.

Reason: Minimum variance of an estimator means variance of any other estimators that can put for population parameter is higher than that of minimum variance estimator.

4)

Answer: 1.96

Reason : It is a two tail proportional normal test. So no need of negative value.

The question here is asked to test whether the proportional is different from 0.5 rather not to check whether it is > or < from 0.5

5)

Answer = 0.0154

Reason: standard error = ✓[(0.5*0.5)/1058] = 0.015371886
