Carlos is designing a video game, and he's concerned that one of the levels is too difficult. He will redesign the level if he has convincing evidence that it takes the average player longer than 45 minutes to complete the level.
He plans on recruiting players to play the level until they complete it, and he'll use their completion times to
perform a significance test.
Let u represent the average completion time for players of this level.
Which of the following is an appropriate set of hypotheses for this significance test?

answer:

c. the third graph

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
