Question

Can someone please show me the steps to this question? Please
Mr. Dunbar's math class averaged poorly on a test, so he gave them a retest. If every person in the class scored 5 points higher on the retest, how would the RANGE of the retest scores differ from the RANGE of the scores on the first test?

Answer 1

@MissSmartiez could you please help me?

Answer 2

do you know what the range means ?

Answer 3

'every person in the class scored 5 points higher on the retest, '

Answer 4

'Mr. Dunbar's math class averaged poorly on a test, '

Answer 5

Connect the dots.

Answer 6

They scored poorly on what? What points did they gain in the retest? What is the range?

Answer 7

So the range on the retest would be 5 points higher.

Answer 8

in statistics , the range is the difference between the max and the min
(is that what we are doing here?)
if so, max+5 - (min +5) = max - min (i.e. the original range)
