A researcher analyzing the determinants of earnings and she has data on 16 occupation categories that exhausts all possibilities. If the researcher runs a regression of earnings on a binary (dummy variable) for all 16 categories, which least-square assumption is violated?
Determine the mean waiting time W for an M/M/2 system when lambda = 2 and μ = 1.2. Compare this with the mean waiting time in an M/M/1 system whose arrival rate is lambda = 1 and service rate is μ = 1.2. Since the arrival rate per server is the same in both cases and service times don’t vary, should the wait times be the same in both cases?
The manager of Cines California affirms that the average duration oftype A comedy films exceed the average length oftype B horror movies in at least 15 minutes. Paracaverify this claim, 15 films of each type are testedunder similar conditions, obtaining that the film ofType A comedy has an average duration of 86.7 minuteswith a variance of 36 minutes, while the film ofType B terror has an average duration of 77.8 minutes with a25 minute variance. Test the manager's claim with theuse of a level of 0.01
A recent study claims that using music in a class enhances concentration and consequently helps students absorb more information. A researcherdecided to test this claim on a smaller group of randomly selected students from three different classes. Each classroom was provided with a different environment for students to study. Classroom A had constant music being played in the background, classroom B had variable music being played and classroom C was a regular class with no music playing. After one month, the researcher conducted a test for all the three groups and ranked their scores. What statistical test would be most appropriate for testing the research hypothesis? Explain your answer.

A study was performed concerning medical emergencies on commercial airline flights. A database was constructed based on calls to a medical communications center from 5 domestic and international airlines representing approximately 15% of the global passenger flight volume from January 2005 to December 2007. There were 11,000 in flight medical emergencies (IFM) among 8,000,000 flights during the study period. Assume that there is at most 1 IFM per flight. Suppose a flight attendant works on 3 flights per day for each of 300 days per year. Also, assume that the flight attendant’s total duration of employment is 20 years. What is the approximate probability that he/she encounter at least 5 IFM’s over a 20 year period?

A researcher uncovers that there is a significant interaction between the factor of marital status (i.e., married or non-married) and participant sex (i.e., male or female) regarding well-being among a sample with n = 6 participants in each condition. A researcher decides to compare the difference in well-being between married men and women. The MSwithin treatments from the original two-factor analysis is MSwithin treatments = 1.00. What is the F-ratio for this comparison using the matrix below, which depicts descriptive statistics regarding married participants? __________________________________________________________________________________________ Participant Sex Males Females __________________________________________________________________ n = 6 n = 6 N =12 M = 4…
A possible important environmental determinant of lung function in children is the amount of cigarette smoking in the home. Suppose this question is studied by selecting two groups: Group 1 consists of 23 nonsmoking children 5−9 years of age, both of whose parents smoke, who have a mean forced expiratory volume (FEV) of 2.1 L and a standard deviation of 0.7 L; group 2 consists of 20 nonsmoking children of comparable age, neither of whose parents smoke, who have a mean FEV of 2.3 L and a standard deviation of 0.4 L. A) What are the appropriate null and alternative hypotheses to compare the means of the two groups? B) What is the appropriate test procedure for the hypotheses in Problem A? C) Carry out the test in Problem B using the criticalvalue method. D) Provide a 95% CI for the true mean difference in FEV between 5- to 9-year-old children whose parents smoke and comparable children whose parents do not smoke.

A) Assuming this is regarded as a pilot study, how many children are needed in each group (assuming equal numbers in each group) to have a 95% chance of detecting a significant difference using a two-sided test with α = .05? B) Answer the question in Problem A if the investigators use a one-sided rather than a two-sided test. Suppose 40 children, both of whose parents smoke, and 50 children, neither of whose parents smoke, are recruited for the study. C) How much power would…
