Aconsumer group claims that the mean acceleration time from 0 to 60 miles per hour for a sedan is 7.9 seconds. a random sample of 33 sedans has a mean acceleration time from 0 to 60 miles per hour of 7.6 seconds. assume the population standard deviation is 2.3 seconds. find the standardized test statistic and the corresponding p-value.

step-by-step explanation:

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.

is there any photos or whatever?
