The following is a list of the amount of time (in minutes) that it
takes various students to get to school by bus:
10 | 14 | 9 | 14 | 25 |
45 | 13 | 21 | 18 | 12 |
7 | 16 | 35 | 30 | 12 |
26 | 24 | 19 | 11 | 20 |
Problem : What is the (mean) average number of minutes it takes to get to school by bus, according to the data?
19.05 minutesProblem : Make a frequency distribution table for the data.
We cover the range with five intervals of length ten minutes:Intervals (in minutes) | Frequency |
0 - 9 | 2 |
10 -19 | 10 |
20 - 29 | 5 |
30 - 39 | 2 |
40 - 49 | 1 |
Total | 20 |
Problem : What is the median number of minutes it takes to get to school by bus, according to the data?
17Problem : Make a histogram for the data, using the frequency distribution table.
Problem : In which time interval do the most students fall? The least?
10 - 19 ; 40 - 50 .Problem : Do more students spend less than 10 minutes on the bus or 30 or more minutes on the bus?
30 or more minutes.Take a Study Break!
