The line plot shows the quiz scores of several students. What is the range of the quiz scores?

There is no overlap between the data.

Step-by-step explanation:

The other statements are not true.

When you draw out the dot plot, you will see that the range for round is greater than the range for round 1, directly contradicting choice 4. You will also notice that the scores for round 1 are more scattered towards the higher scoring points, while round 2 scores are all below 8. Thus, choice 2 and 3 are not right so choice 1 is the correct choice.

The inference that can be made using the dot plot is:

    The range of round 1 is greater than the round 2 range.

Step-by-step explanation:

Round 1:

Score                Frequency

  1                          0

  2                          2

  3                          3

  4                          2  

  5                          1

Hence, the minimum score of Round 1 is: 2

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                      =5-2

                       =3

Similarly, Round-2

Score                Frequency

  1                          0

  2                         0

  3                          0

  4                          4  

  5                          4

Hence, the minimum score of Round 1 is: 4

maximum score is: 5

Hence, Range=Maximum value-Minimum score

                      =5-4

                       =1

The scores of round 2 are higher than round-1.

Since round 2 have a higher frequency for higher scores as compared to round-1.

Hence, Range of round 1 is greater than the range of Round-2.

I believe it is B, the ranges are the same.

Step-by-step explanation:

The first one adds up to 34 while the second adds up to 36.  This puts C and D to false.  I did the test myself and A was incorrect.  Plus, 34 and 36 are very close, so their range must be the same.  Sorry if incorrect e.e

The range of round 1 is greater than the round 2 range.

Round 1: 9 - 5 = 4

Round 2: 7 - 5 = 2

Therefore, Round 1's range is greater by 2

This is the only one that works. It is not A, because there is overlap (5-7)

The others do not work, because they contradict themselves.

hope this helps

answer is b hope this helps :) the other person that answered is just a mean person

Option: D is the correct answer.

        D. The range of round 1 is greater than the round 2 range.

Step-by-step explanation:

Round-1

       Score                Frequency          Total

         5                           1                       5×1=5

         6                           4                       6×4=24

         7                            2                      7×2=14

         8                            2                      8×2=16

         9                            1                       9×1=9

                                              Total--      68

Hence, total score obtained in Round 1 are: 68

Round-2

       Score                Frequency          Total

         5                           3                      5×3=15

         6                           1                       6×1=6

         7                            6                      7×6=42

                                              Total--      63

Hence, total score obtained in Round 1 are: 63

Hence, Round-1 scores were higher than Round-2 scores,=.

Hence, option: B and C are discarded.

Also, there is a overlap in the data ( since there are some scores which are obtained in both the rounds)

Hence, option: A is discarded.

Now,

Range of round-1 score is:

Maximum score-Minimum score

=9-5

=4

Hence, Range of Round-1 is: 4

Similarly Range of Round-2 is: 2

( Since, Maximum score in round-2 is: 7

and Minimum score is: 2

Hence, Range=7-5=2  )

                Hence, the correct answer is:

       D. The range of round 1 is greater than the round 2 range.

answer is b hope this helps :) the other person that answered is just a mean person

Option: D is the correct answer.

        D. The range of round 1 is greater than the round 2 range.

Step-by-step explanation:

Round-1

       Score                Frequency          Total

         5                           1                       5×1=5

         6                           4                       6×4=24

         7                            2                      7×2=14

         8                            2                      8×2=16

         9                            1                       9×1=9

                                              Total--      68

Hence, total score obtained in Round 1 are: 68

Round-2

       Score                Frequency          Total

         5                           3                      5×3=15

         6                           1                       6×1=6

         7                            6                      7×6=42

                                              Total--      63

Hence, total score obtained in Round 1 are: 63

Hence, Round-1 scores were higher than Round-2 scores,=.

Hence, option: B and C are discarded.

Also, there is a overlap in the data ( since there are some scores which are obtained in both the rounds)

Hence, option: A is discarded.

Now,

Range of round-1 score is:

Maximum score-Minimum score

=9-5

=4

Hence, Range of Round-1 is: 4

Similarly Range of Round-2 is: 2

( Since, Maximum score in round-2 is: 7

and Minimum score is: 2

Hence, Range=7-5=2  )

                Hence, the correct answer is:

       D. The range of round 1 is greater than the round 2 range.

The range of round 1 is greater than the round 2 range.

Round 1: 9 - 5 = 4

Round 2: 7 - 5 = 2

Therefore, Round 1's range is greater by 2

This is the only one that works. It is not A, because there is overlap (5-7)

The others do not work, because they contradict themselves.
