er student: 203,245,237,233,90,100,100,277,265,264,265,285,288,291, 291,290,300,224,200,257,290,279,266,288 What is the mean number of jumps, rounded to the nearest hundredth?
The mean number of jumps in this competition is 242.83.
How I determined this answer: In order to find the mean, first you must add up all of the given numbers together: 203+245+237+233+90+100+100+277+265+264+265+285+288+291+291+290+300+224+200+257+290+279+266+288=5,828. Now that you know the total number of jumps made, the next step is to count the total number of numbers given. Since there is a total of 24 numbers, next you must divide. So, 5,828 ÷ 24 = 242.83333333. Finally, round 242.83333333 to the nearest hundredths place, or 242.83.
