Question Suppose the two islands in Problem 2 agree that the terms of trade will be 1 ton of pineapples for 1 ton of pearls and that trade soon results in an exchange of 10 tons of pineapples for 10 tons of pearls. 1. If Alpha produced 6 tons of pearls and 15 tons of pineapples and Beta produced 30 tons pf pearls and 8 tons of pineapples before they decided to trade, how much would each be producing after trade became possible? Assume that the two countries specialize just enough to maintain their consumption of the item they export, and make sure each island trades the item for which it has a comparative advantage. 2. How much would the combined production of pineapples increase for the two islands due to trade? How much would the combined production of pearls increase? 3. How could both islands produce and consume even more?

Biostatistics ESSAY A firm investigates the length of telephone conversations of their office staff. Ten consecutive conversations had lengths, in minutes: 10.7, 9.5, 11.1, 7.8, 11.9, 4.1, 10.0, 9.2, 6.5, 9.2. Derive a 95% confidence interval for the mean conversation length. Test whether the mean length of a conversation is eight minutes.(25 MARKS)

P3.5 The sales revenue, food cost of sales, and guests served for a small fast- food carryout division of a restaurant for the past six months are given below. Sales Month Cost of Revenue Guests Served Sales, Food 1 2. 4 $258,200 274,800 285,600 289,400 298,300 304,600 $ 96,200 104,300 110,500 113,100 118,900 123,700 10,200 10,400 10,300 10,100 10,400 10,500 6 For each of the six months calculate average check and average costs of sales food. Using these averages, calculate an index number. Set the in- dex for month 1 at 100 and complete index numbers for the remaining five months. With the index numbers identified, convert sales revenue and cost of sales food from historic to current dollars.

A cylindrical rock sample has a length of 6 cm, a diameter of 4 cm, and a dry weight of 166.4 g. When fully saturated with an oil of density 0.85 g/cm3, the weight of this sample is 176.9 g. Assuming constant temperature, find: i) The porosity of the sample ii) The pore compressibility of the sample, given that 0.2 cm of oil leaves the sample when a pressure of 3200 psig is applied on it iii) The amount of oil that can be extracted from the sample when a pressure of 2000 psig is applied on it
