Consider a random experiment of observing the direction for each of 4successive vehicles that are taking a particular freeway exit. There are 3possibilities for every vehicle: the vehicle can turn right (R), turn left (L), or gostraight (S).How many possible outcomes are there in the sample space for this randomexperiment?Oa. N = 81Ob. S = (R, L, S)c. None of the answers.

Many college and university students obtain summer jobs. A professor wanted to determine whether students in different degree programs earn different amounts. She randomly selected five students in each of the 4 university programs and asked them to report what they earned the previous summer (in thousands of dollars). The following partially filled-in ANOVA table was obtained. Fill-in the rest of the table. (Use exact values for df and round all other numbers to 2 decimal places, if needed.)
