Answer:

The range will be "-2.0% to 14.8%". A further explanation is given below.

Explanation:

According to the question,

For 68%, the range seems to be +/- 1 standard deviation of the mean. So that the upper as well as the lower range will be:

Upper range,

= [tex]6.4 - 8.4[/tex]

= [tex]-2.0[/tex] (%)

Lower range,

= [tex]6.4 + 8.4[/tex]

= [tex]14.8[/tex] (%)

So that the range would be between "-2.0% to 14.8%".
