To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. Refer to Exhibit 12-4. The calculated value for the test statistic equals: Select one: a. 0.01 b. 0.75 c. 4.29 d. 4.38 Exhibit 12-4 In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. Refer to Exhibit 12-4. The hypothesis is to be tested at the 5% level of significance. The critical value from the table equals: Select one: a. 1.645 b. 1.96 c. 5.991 d. 7.815 Exhibit 12-4 In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College.

In order to test the assumption of a Poisson distribution, a random sample of 150 ten-minute intervals was taken. You are given the following observed frequencies: Number of Cars Arriving in a 10-Minute Interval Frequency 0 3 1 10 2 15 3 23 4 30 5 24 6 20 7 13 8 8 9 4 150 Refer to Exhibit 12-6. The p-value is: Select one: a. Greater than 0.1 b. Between 0.05 and 0.1 c. Between .025 and .05 d. Between .01 and .025 Exhibit 12-6 The owner of a car wash wants to see if the arrival rate of cars follows a Poisson distribution.
