Mr. Lew recorded the average length, in minutes, of phone calls received at work. He recorded the data in the box plots below. A box plot titled Professional Call Length in Minutes. A number line goes from 0 to 11. The whiskers range from 2 to 10, and the box ranges from 3 to 8. A line divides the box at 4. Professional Call Length in Minutes A box plot titled Personal Call Length in Minutes. A number line goes from 0 to 11. The whiskers range from 1 to 11, and the box ranges from 4 to 6. A line divides the box at 5. Personal Call Length in Minutes Which is an accurate comparison of the two data sets? Time spent on professional calls is typically shorter and more consistent than time spent on personal calls. Time spent on professional calls is typically shorter but less consistent than time spent on personal calls. Time spent on professional calls is typically longer but more consistent than time spent on personal calls. Time spent on professional calls is typically longer and less consistent than time spent on personal calls.

Time spent on professional calls is typically shorter but less consistent than time spent on personal calls.

Step-by-step explanation:

Professional calls are typically shorter (Median = 4 min) than personal calls (Median = 5 min).

However, they are less consistent (IQR = 5 min) than personal calls (IQR = 2 min).

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
