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…

Treating people adequately for hypertension has been dif- ficult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who do know are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treat- ment by taking the right number of pills. 1 If the preceding 50% rates were each reduced to 40% by a massive education program, then what effect would this change have on the overall mortality rate among true hypertensives; that is, would the mortality rate decrease and, if so, what percentage of deaths among hypertensives could be prevented by the education program?

The doctor diagnosed Manila with a severe dry cough. A mucolytic solution was prescribed and to be administered for seven days. The prescription states, “Mucolytic, XYZ Brand, 60 ml, dosage-1 teaspoon 1 hour before a meal, 3x a day”. Now, Filipina is skeptical of the dosage mentioned in the prescription regarding the proper amount of medicine to be administered to her daughter. If you are Filipina, how are you going to make sure that your daughter will not have an overdose or underdose of the medicine prescribed? Apply the principle of accuracy and precision in the problem.How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers placed 104104 newly laid eggs in a hot environment, 5656 in a neutral environment, and 2727 in a cold environment. Hot duplicates the warmth provided by the mother python. Neutral and cold are cooler as when the mother is absent. The results: 7575 of the hot eggs hatched, along with 3838 of the neutral eggs and 1616 of the cold eggs.26 Make a two‑way table of "environment temperature" against "hatched or not." Fill in the values ?-?�-� in the answer boxes provided. Give your answers as whole numbers. Temperature Cold Neutral Hot Hatched ? ? ? Did not hatch ? ? ? ? =
