Q4) Assume you administered a test in September and then again in November. You obtained a correlation coefficient of 0.55 between the two administrations. What does this mean? (Short Answer required)
The Sydney Airport Commission set a performance target of 26 minutes for the time taken for passengers to claim their luggage at domestic terminals. In order to monitor performance a study was conducted by taking a random sample of 200 passengers disembarking from Sydney airport. If the study found a p-value of 0.5 what was the sample mean time taken by passengers to claim their luggage? (Your answer should be correct to one decimal place.)

Taubman et al., (2014) used data collected in the Portland, OR metro area to study the Impact Medicaid on emergency department (ED) use. The figure below shows the percent of respondents who have been to the ED at all (left hand side of the figure) and the average number of ED visits (right hand side of the figure). The dark blue bars represent the mean for the control group, and the light blue bars add in the "Medicaid" effect found in the paper. The black "capped" bar represents the confidence interval for the Medicaid effect.

UBC coaching center has two branches in Dhaka: one in Dhanmondi (Branch A) and another one in Mohammadpur (Branch B). To understand their students' performance, the coaching center conducts the same test in both branches. A sample of 8 students have been selected from branches A and B respectively, and the following table shows data on their performance. Use appropriate non-parametric methods on the data to find out whether there is a statistically significant correlation between the ranks of the students’ performance of the two branches.?
T or F A household is frequently used in analyses because more consistent data are usually collected at that level.
Which of the following is true of heteroskedasticity? a) The R-squared statistic is affected by the presence of heteroskedasticity b) Heteroskedasticty causes inconsistency in the Ordinary Least Squares estimators c) The OLS estimators are not the best linear unbiased estimators if heteroskedasticity is present d) It is not possible to obtain F statistics that are robust to heteroskedasticity of an unknown form
You estimated a linear regression model with 3 explanatory variables using a sample of 29 observations. You are asked to test the overall significance of the model.the F-statistics calculated is equal to 2.567 and the F-critical at 5% level is 3.028. The p-value of the test can be expressed as: Select one: O a. P(F(3,25)<=2.567) O b. 1-P(F(3,25)<=2.567) O c. P(F(3,25)<3.028) O d. 1-P(F(3,25)<33.28)
Tourism patterns are difficult to forecast; they normally vary from country to country and sometimes even between places quite close to each other. In Hong Kong, a survey asked 1,600 people their favorite Asian destination for a short holiday. The results were as follows: 43% go to China, 23% go to Thailand, 20% go to the Philippines, 5% go to Cambodia, and the rest choose other countries. The same survey has been carried out in Macau, China only 1 hour from Hong Kong by jet boat, and the results were as follows: 48%, China; 20%, Thailand; 22%, the Philippines; 3%, Cambodia; and the remaining, other destinations. Would you conclude that the patterns are the same in the two cities?
QUESTION 3 (Figure: US Business Cycle Expansions and Contractions) From the data on averages for all cycles we can conclude that over time: Business cycles data.pdf O The number of cycles during 1945-2020 exceeded the number of cycles during 1854-1919. The number of cycles during 1919-1945 exceeded the number of cycles during 1945-2020. The average duration of contractions during 1854-1919 was shorter than the average duration of contractions during 1945-2020. The average duration of expansions during 1854-1919 was shorter than the average duration of expansions during 1945-2020.
