The no. 1 basketball team made 72% of its free throws over the past 5 seasons and shot 450 free throws in total. The
no. 2 team made 64% of its free throws over the past 5 seasons and shot 550 free throws in total. You randomly select
40 free throws from each team and record whether they made the shot. Let o, -, be the difference in the sample
proportions of successful free throws where o, is the proportion of free throw shots made by the no. 1 team and is
the proportion of free throw shots made by the no. 2 team.
Determine the mean of the sampling distribution of Ô, - Ôz. Enter your answer as a decimal rounded to the
hundredths place.
The mean difference of the sampling distribution of the difference in the proportion of free throw shots made between
the no. 1 and no. 2 teams is

Which of the following statements are true? (select all that apply.) a quasi-static process is one in which the system is never far from being in equilibrium. when a system can go from state 1 to state 2 by several different processes, the amount of heat absorbed by the system will be the same for all processes. the internal energy of a given amount of an ideal gas depends only on its absolute temperature. when a system can go from state 1 to state 2 by several different processes, the work done on the system will be the same for all processes. when a system can go from state 1 to state 2 by several different processes, the change in the internal energy of the system will be the same for all processes. for any substance that expands when heated, its cp is greater than its cv.
