Question

Can you please help me out with this part of the problem I had already asked for help for this problem already but they answered the wrong part of the problem and they gave me all wrong answers for the part they did answer. Please help me with this part of the problem. ANd if you can please also help me finding the point estimate. I asked a seperate question for this too and they gave me wrong answers. THis part of the problem that I need help is the first image without the highlighting I added the second picture for your reference.
