Cynthia rounds a number x to one decimal place the result is 6.3 write down the error interval for x

6.25 ≤ x ≤6.34

Step-by-step explanation:

Given that:

Number, x rounded to 1 decimal place = 6.3

The lowest value number x could be is ;

6.25, rounding 6.25 to 1 decimal place = 6.3

The highest value number x could be is ;

6.34, rounding 6.34 to 1 decimal place = 6.3

Hence, the error interval for X is

Lowest possible value ≤ x ≤ highest possible value

6.25 ≤ x ≤6.34

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
