The National Safety Council (NSC). collects data on all kinds of accidents, including automobile collisions. Below is a breakdown of auto collisions in the United States by day of the week. Wednesday Day Percent of collisions Sunday Monday Day 15.7 Sunday 12.5 Number of 517 collisions Monday Tuesday 446 12.6 So, 15.7% of collisions occur on Sunday. Here is data from last year on the number of fatal auto collisions by days of the week from the state of California Tuesday 404 13.1 ● null and alternate hypotheses test statistic, critical value and/or p-value Wednesday So, there were 517 fatal collisions on Sundays last year. ● expected counts • reject or fail to reject the null hypothesis conclusion in plain English 438 Thursday 13.5 Friday 15.4 Thursday Friday 444 Saturday 522 17.2 Saturday 1. Does the distribution of fatal auto accidents in California differ from the distribution for all accidents in the United States? 545
