Aclass of fourth graders takes a diagnostic reading test and the scores are reported by reading level. the 5-number summaries for the 14 boys and 11 girls are shown:
boys: 2.0, 3.9, 4.3, 4.9, 6.0
girls: 2.8, 3.8, 4.5, 5.2, 5.9
which group generally did better on the test?

The girls had a higher average in the reading test than the boys.

Step-by-step explanation:

To find the solution, you need to find the mean (average) of the group of boys and group of girls each. The mean of numbers can be found by dividing the sum of all numbers by the amount of numbers there are.

Lets start by finding the mean of the boys group. Find the sum of all numbers:

Now divide the sum by how many numbers, or in this case, how many boys did the test:

The mean, average, of the tests conducted by the group of boys is 4.22.

Repeat the same for the girls group:

The mean, average, of the tests conducted by the group of girls is 4.44.

Compared to 4.22, 4.44 is bigger than 4.22.

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.
