In horse racing, a “trifecta” occurs when a bettor wins by selecting the first three finishers in the exact order (1 St place, 2nd place, and 3rd place). How many different trifectas are possible if there are 14 horses in a race?
In one statistics class, students were given one homework assignment. The professor asked students to find an example of a multinomial population and then to develop a hypothesis test. One student found an example – He selected four classes in fall 2010: Management, Accounting, Finance, and Economics. He computed the proportion of students who received an A grade for each class in fall 2010. The proportion of students who received an A grade in Management (M), Accounting (A), Finance (F), and Economics (E) is 0.45, 0.25, 0.3, and 0.2, respectively. In fall 2011, a new hired Economics professor teaches Economics. The student wants to study whether or not the new Economics professor will affect the proportion of students who will receive an A grade in these four classes in fall 2011. The enrollments of these four classes are 54, 48, 52, and 64, respectively. Therefore, this student formulates the null hypothesis: P(M) = 0.45, P(A) = 0.25, P(F) = 0.3, and P(E) = 0.2; while the alternative…
A professor wants to know which type of instructional mode students had more satisfaction. The professor randomly selected n = 5 students from each of the following types of classes: online only, hybrid, and face-to face only. Student were given a satisfaction survey. Are their differences in student satisfaction among the different instructional modes. The data are below: Online Hybrid Face-to-Face 3 3 4 3 3 1 3 1 3 2 2 2 2 1 3 Calcuate the Sum of Squares total (SStot).

1. Consumer researchers are studying airline fares from four major airlines. They wish to investigate whether the population mean airline fare is the same for the four airlines. To control for the variation in fares across different locations, they chose 5 destinations and obtained fares from the four airlines for each of the 5 destinations. From these data they found that the sum of squares for the destinations was 648242.5, the sum of squares for error was 7377.5, and the total sum of squares was 663230.0 . a) What experimental design has been used? b) Use the above information to conduct a test of the null hypothesis that mean airline fares are equal for the four airlines. State the null and alternative hypotheses, fill out the ANOVA table, compare your F statistic for the airline effect to a tabled F value and state the conclusion of your test. Use a significance level of a = .05. c) Based on the results from this study, did the inclusion of the destination as a factor in the…
A national nursing organization is lobbying congress for sunding to hire more nurses nationwide. One of the arguments is that nurses, on average, work significantly longer than full time duty, assuming full time is 40 hours a week. A sample of n=9 nurses had the following work hours last week: 43, 45,48,41,45,50,50,53,48 Calculate the sum of squares of work hours for the sample.
An experiment to determine the effect of mold temperature on tensile strength involved three different alloys and five different mold temperatures. Four specimens of each alloy were cast at each mold temperature. With mold temperature as the row factor and alloy as the column factor, the sums of squares were: SSA = 69,738, SSB = 8958, SSAB = 7275, and SST = 201,816. a) Construct an ANOVA table. You may give ranges for the P-values. b) Is the additive model plausible? Explain. c) Is it plausible that the main effects of mold temperature are all equal to 0? Provide the value of the test statistic and the P-value. d) Is it plausible that the main effects of alloy are all equal to 0? Provide the value of the test statistic and the P-value.
Your instructor wonders which method of getting to school is faster. She records the time it takes to get to school via bus, driving the side streets, driving on the highway, and bicycling, using 10 trips for each method. After collecting her data and analyzing the results, she reports that the F-ratio is 8.76. What are the null and alternative hypotheses? How many degrees of freedom does the group sum of squares have? How about the error sum of squares? Assuming that the conditions required for ANOVA are satisfied, what is the P-value? What would you conclude? What else about the data would you like to see in order to check the assumptions and conditions?
