部分真題預覽：

Part A： 1）The graph below shows the monthly average temperatures, in degrees Fahrenheit, for two cities–Madison,Wisconsin, and Juneau, Alaska–in the United States.

1. Based on the graph, compare the two cities with respect to the monthly average temperatures over the year. Address both similarities and differences in the overall patterns.
   Similarities:
   Differences:
2. For which of the two cities is the standard deviation of the 12 monthly average temperatures greater? Justify your answer without performing any calculations.

Part B： 6）The United States one-cent coin is called a penny. Banks often use a machine to count and package pennies in rolls of 50 pennies. Occasionally a machine malfunctions and begins putting fewer than 50 pennies in each roll. The quality control inspector at a certain bank wants to investigate whether its machine is functioning properly but does not want to break open the rolls to count pennies. The inspector will measure the weight of a roll of pennies to test the following hypotheses.
H₀ :The machine is putting 50 pennies in each roll.
H_a :The machine is putting fewer than 50 pennies in each roll.

1. For testing the hypotheses above, describe what a Type II error would be and describe a consequence of making a Type II error.
   Description of error:
   Consequence:
   For pennies produced since 1983, the distribution of weight is approximately normal with a mean of 2.5 grams and a standard deviation of 0.04 gram. Assume that the pennies in a roll can be considered a random sample of pennies produced since 1983.
   Let the random variable W represent the total weight of a roll of pennies. Ignore the weight of the packaging of the roll.
2. Describe the distribution of W if the selected roll contains 50 pennies.
