Justin uses an alarm clock to wake up in the mornings, but when he wakes up, he is frequently tired. he’s heard that if he slept without an alarm clock, he might wake up more refreshed, but justin is afraid that he would be late to school. what advice could justin with his problem?

possible "If Justin went to sleep earlier, he could eliminate the need to wake up with an alarm clock. His tiredness probably stems from not getting enough sleep. If his body was fully rested, it would wake up on its own. Combining going to bed earlier with getting rid of the alarm clock (except as an emergency device for when he accidentally slept in) would probably improve Justin’s sleep."

no

explanation:

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
