Answer 1

Answer #1

2. Option 2.

First is the mean square error and next is the variance.

(By conventional formual. Since theta-theta hat is the error so taking it's mean sqaure gives us mean square error.)

3. Option 4.

The criteria is reject Ho when pvalue < alpha. Secondly if the Confidence interval does not include the values specified by Ho, we can reject Ho.

4. Option 4.

Pvalue is the area at the tails at the point of critical value. Since it is two tailed test, area under pvalue will be on both the ends.

5. Option 4.

Since alternative is right tailed, it is sufficient to determine one sided confidence interval and conclude.
