Can someone please help me solve the following question based on the blow provided information:

Q. 4. Determine the expected value of the amount that could be paid to Louis Matthew in a settlement. Use the 75% probability figure. Also, determine a maximum and minimum expected value for the settlement figure based on the confidence interval above. Be sure to include all of the damages Louis Matthew will be able to recover. How would you interpret your expected values?

The total possible expected value can be 5800, now can someone help me how to understand the minimum and maximum expected value based on the below provided information.

Thank you!

Q. 3. Consider the sample of 850 past negligence cases. Suppose you are willing to let the 75% estimate be within .03 (3%) of the true proportion. You are willing to assume a 95% confidence.

a. Is 850 an adequate sample size for the estimate of 75%? Show why or why not.

The standard deviation is based on the propotion is: (p(1-p)) = 0.433013.

Calculates the sample size to get the following confidence interval: 0.75 0.03.

= 1 - 0.95 = 0.050.

Z_(1-/2) = Z_(1-0.050/2) = Z_0.975 = 1.959964.

The required sample size is:

n = Z²_0.975*p(1-p)/MOE² = 1.959964²*0.75(1-0.75)/0.03² =801.

Rounded up from: 800.303921.

yes 850 is adequate

b. Construct a 95% confidence interval on the estimate of 75%. How would you interpret it?

Thank you. Only very expert information please.
