You want to see if it makes a difference which lane to be in when there is traffic. You randomly observe 372 cars as they pass by on the four lane freeway. The results are displayed in the table below. Use a level of significance of a = 0.01. a. Complete the rest of the table by filling in the expected frequencies: Frequency of Cars in Each Lane Outcome Frequency Expected Frequency Lane 1 89 Lane 2 98 Lane 3 92 Lane 4 93 b. What is the correct statistical test to use? Select an answer c. What are the null and alternative hypotheses? Ho: OThe distribution of traffic is not uniform. CThe traffic and lanes are independent. OThe distribution of traffic is unifom. The traffic and lanes are dependent. Hi: OThe distribution of traffic is unifom. OThe traffic and lanes are independent. O The traffic and lanes are dependent. O The distribution of traffic is not uniform.
