You want to see if it your cholce of lane makes a difference in how many cars you have to deal with. You randomly observe 267 cars as they pass by on the three lane freeway. The results are displayed in the table below. a. What are the null and alternative hypotheses? Ho: Select an answer H: Select an answer b. Complete the rest of the table by filling in the expected frequencies: Outcome Frequency Expected Frequency Lane 1 82 Lane 2 95 Lane 3 90 Frequency of Cars in Each Lane c. Do a hypothesis test with a = 0.05. Give either the test statistic, X, or the p-value (Identify which one you're giving). Then, give your conclusion based on the original question.

The distribution of majors at the college is shown below. Major Math/Science Arts and Humanities Business and Economics Others Percents 24 33 34 9 Suppose a random sample of 400 athletes from the college are surveyed. The table below shows the results of the survey. Major Math/Science Arts and Humanities Business and Economics Others Frequency 95 146 118 41 What can be concluded at the 0.05 level of significance? Perform the hypothesis test. H0: The distribution of majors for athletes at the college is the same as the distribution of majors for the general population.
