<u>The range</u> is the an interval on the y-axis where the function is defined.
You can see that your function is y-wise going all the way down to negative infinity but then stops and continues the path along 2 on the upper bound.
The inequality describing the interval is thusly B,

Hope this helps :)

Answer:
Null hypothesis: the variance in hours of usage for talking is not greater than the the variance in hours of usage for internet.
: 
Alternative hypothesis: the variance in hours of usage for talking is greater than the the variance in hours of usage for internet.



Step-by-step explanation:
Let
and
be the two variables that represents the battery life in hours for talking usage and battery life in hours for internet usage respectively.
The hypothesis can be formulated as:
Null hypothesis: the variance in hours of usage for talking is not greater than the the variance in hours of usage for internet.
: 
Alternative hypothesis: the variance in hours of usage for talking is greater than the the variance in hours of usage for internet.

The standard deviation for the battery usage for talking is :

The standard deviation Is:




The standard deviation for the battery life usage for the internet is :




Thus; the standard deviation is:
