The average price for a movie ticket in a certain country in 2018 was ​$9.73. A random sample of 26 movie ticket prices in a major city in that country had a sample mean of ​$13.28 with a standard deviation of ​$3.43. a. Do we have evidence that the price of a movie ticket in that city is different from the national​ average? Use a significance level of 0.05. b. Construct a 95​% confidence interval for the price of a movie ticket in that city. How does your confidence interval support your conclusion in part​ (a)?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
