12. Household content insurance claims are modeled by a Weibull distribu- tion with parameters c> 0 and y=2. (a) A random sample of 50 such claims yields 50 50 = 13,500 and 1 4,500,000. Calculate the method of moments estimator ē and the method of maximum likelihood estimate ĉ of c using this information. Determine an approximate 95% confidence interval for e based on maximum likelihood. TABLE 2.8 Portfolio of 120 claims.

(b) If a deductible of 200 is introduced, estimate (using maximum like- lihood) the reduction in the proportion of claims to be made.

I'm sorry , im not fullying  understanding how you got the second answer . Can you break it down in steps please

I am not quite sure what you did in this question even though the answer is right. Is it possible to use a pen instead of typing ? That can be a great help. Thanks.

Can i get the explanation please?
