A scientist is about to collect data to compute a 95% confidence interval, but he is unsure of what a 95% confidence interval really means. Help him out by filling in the blanks. Before a sample is chosen, there is a 95% that the sample will produce an interval containing the true mean value. After a sample has been chosen, there is 95% that the interval produced by the sample will contain the true mean value.

a. probability/probability

b. confidence/confidence

c. confidence/probability

d. probability/chance

e. probability/confidence

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.
