Answer 10

The two box plots show the scores from Mrs. Clark's first and second blocks on a 60 point assignment. What is the range for second block?


50

15

25

40

Answer 11

You have to look at the whiskers of the box plot to see the whole range - they start at 10 and end at 60, so the range should be 50.

Answer 12

part b- What is the inter-quartile range for first block?
part c- Which class had at least one outlier?
part d- Which class had the highest median?

Answer 13

Interquartile range is the range from the beginning to the end of the boxes. So for the first block, that should be between 35 and 50 so the range is 15.

Answer 14

If you look at the box plots, you should see some amount of symmetry if there are no outliers. If there is asymmetry, it stands to reason that there is an outlier. Neither block looks symmetric, but I am thinking that block 1 looks more asymmetric.

Answer 15

The median is the red line in the box plot, so the 1st block had a higher median.

Answer 16

thank you sooooooo much!

Answer 17

The data represents the miles per gallon (mpg) for vehicles manufactured by a company in the past five years. Are there any outliers for the data? Data: 28.7, 25.5, 21.8, 21.6, 20.5, 16.7, 16.3, 15.4, 13.9

Answer 18

I am thinking that my answer to c may not be correct; I don't know a lot about outliers, so I can't help with the next question. Sorry...

Answer 19

its okay!
