Question

Tim drives the Grand Avenue bus route. He counts the total number of people who ride the bus each week for 5 weeks. How many more people need to ride the bus in week 6 to increase the mean number of riders per week by 10?
Data:

WEEK NUMBER OF PEOPLE
1 16,325
2 18,140
3 17,362
4 16,697
5 16,789

Answer 1

So, you do this, find the mean for the first five weeks, (16325+18140+17362+16697+16789)/5=17062.6, then add ten to that cause that will be your new mean. then change 5 to a 6 and +x on top, then solve for x to find your answer, so (16325+18140+17362+16697+16789+x)/6=17072.6, then x=17122.6 is your answer
