An analysis of road accident data in India was undertaken, and the results published in the Journal of Big Data (Vol. 2, 2015). For a particular cluster of roads, the hourly numbers of accidents totaled over a recent 5-year period are listed in the next table. (These results are adapted from a figure in the journal article.) Create a scatter plot of the data, with number of accidents on the vertical axis and hour on the horizontal axis. What type of trend (if any) do you detect in the data?

Hour .................Number

1 .................125

2 .................148

3 .................159

4 .................270

5 .................281

6 .................295

7 .................302

8 .................216

9 .................225

10 .................353
