Que.11. Why LM curve would become flatter.?

Que.5,31,40,54, and 60.

Please help :(

@Aish

3. Just take arbitary values. n=400(given)
CI=mean+_Z*sigma/root n
take mean as 10 and sd as 4.Now compare.

11.Just plot the Lm Curve .You will get it.

31.The whole box will be pareto efficient. Draw diagram .
