2. Formulate a statistical model for each of the situations below, in terms of one or more iid samples. If a model has more than one parameter, specify which parameter is of primary interest. (a) A ship builder buys each week hundreds of tins of paint, labeled as containing 20 liters. The builder suspects that the tins contain, on average, less than 20 liters, and decides to determine the volume of paint in nine randomly chosen tins. (b) An electronics company wishes to examine if the rate of productivity differs signifi- cantly between male and female employees involved in assembly work. The time of completion of a certain component is observed for 12 men and 12 women. (c) The head of a mathematics department suspects that lecturers A and B differ signifi- cantly in the way they assess student work. To test this, 12 exams are both assessed by lecturer A and B. (d) To investigate if the support for the Honest party is the same in two different cities, one hundred voters in each city are asked if they would vote for the Honest party or not. 2.
