(b) A survey was carried out by government through ministry of labor, one of the aims
being to discover to what extent minimum wage was being implemented by firms on
the copperbelt. 32 firms had emplovees getting below and above the minimum wage,
65 firms had just one of these attributes and 90 firms paid its employees above the
minimum wage. If 22 firms did not give out full information, how many firms were
included in the survey?

Two different types of polishing solutions are being evaluated for possible use in a tumble-polish operation for manufacturing interocular lenses used in the human eye following cataract surgery. Three hundred lenses were tumble polished using the first polishing solution, and ofthis number, 253 had no polishing-induced defects. Another 300 lenses were tumble-polishedusing the second polishing solution, and 196 lenses were satisfactory upon completion.(a) Is there any reason to believe that the two polishing solutions differ? Use α = 0.01

John is a manager at a small English Bakery that sells gooseberry pies. Currently, each of his three employees, agent 1, agent 2 and agent 3, work independently on full commission. Assume to begin with that individual effort is observable, and that total output is given by Q = 10(E1 + E2 + E2). Agents are paid a salary of a + Qi (where Q1 = 10 E1 = output from agent 1; Q2 = 10E2 = output from agent 2 = 10E2 and so on). Each agent has an alternative utility level of 10 units, and the cost of effort C(E) = E2. Answer the following questions.a) Given this compensation scheme, what is the (privately) optimal amount of effort for agent 1?b) How many pies does she make?c) What must the fixed portion of agent 1’s income (a) be for her utility on this job to exactly equal 10?d) What is agent 1’s total income in the above situation?e) Check to see that agent 1’s utility level is in fact 10 when she gets this total income and chooses her effort optimally.f) What is the profit for the firm that…

Suppose a company charges a premium of $150 per year for an insurance policy for storm damage to roofs. Actuarial studies show that in case of a storm, the insurance company will pay out an average of $8000 for damage to a composition shingle roof and an average of $12,000 for damage to a shake roof. They also determine that out of every 10,000 policies, there are 7 claims per year made on composition shingle roofs and 11 claims per year made on shake roofs. What is the company’s expected value (i.e., expected profit) per year of a storm insurance policy? What annual profit can the company expect if it issues 1000 such policies? Determine the probability of a composition shingle roof claim out of 10,000 = ______ Determine the probability of a shake roof claim out of 10,000 = ______ How many claims are made out of 10,000? = _______ What is the probability of no claims out of 10,000? = _______ How much does each shingle roof claim cost the company, don’t forget each person pays $150…
