The California Highway Patrol (CHP) routinely compiles car crash data in California. The accompanying table shows shows a portion of the data for Santa Clara county. It shows information on the type of car crash (Head-On or Not Head-On) and light (Daylight or Not Daylight). (You may find it useful to reference the appropriate table: chi-square table or Ftable) ZpictureClick here for the Excel Data File a. Use the data to construct a contingency table. b. Specify the competing hypotheses to determine whether crash type is related to light. H0: Crash Type and Light Condition are dependent; HA : Crash Type and Light Condition are independent H0: Crash Type and Light Condition are independent; HA : Crash Type and Light Condition are dependent c-1. Calculate the value of the test statistic. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.) c-2. Conduct the test at the 1% significance level and make a conclusion.
