- Recently the European Community (EC) decided to lower its subsidies to makers of pasta. In deciding by what amount to reduce total subsidies, experiments were carried out for determining the possible reduction in exports, mainly to the United States, that would result from the subsidy reduction. Over a small range of values, economists wanted to test whether there is a positive correlation between level of subsidy and level of exports. A computer simulation of the economic variables involved in the pasta exports market was carried out. The results follow. Assuming that the simulation is an accurate description of reality and that the values obtained may be viewed as a random sample of the populations of possible outcomes, state whether you believe that a positive rank correlation exists between subsidy level and exports level over the short range of values studied Qarrow_forwardIs auto correlation possible in cross-sectional data? why?arrow_forwardUBC coaching center has two branches in Dhaka: one in Dhanmondi (Branch A) and another one in Mohammadpur (Branch B).

- The management of a large firm would like to know something about employee morale and the other variables to which it may be related. To study these relationships, each employee in a simple random sample of 27 employees is interviewed and tested to obtain information concerning morale level and the average number of satisfying extra work social contacts experienced during a week. Whether or not the duties the employee usually performs are appropriate to the job title is also determined. The dependent variable Y is measure of morale, the quantitative independent variable, X1 is average number of social contacts, and the following dummy variable coding is used to quantify the qualitative variable: X2 = 1 if yes, X2 = 0 if no. The model including dummy variable and the interaction term was being estimated and a part of computer outputs is below: beta std error t p-value 95% CI for B Lower bound Upper bound Constant 260 134.308…arrow_forwardCelebrity endorsement has become a popular choice in advertising due to the its originality and the celebrity’s attractiveness that make a big impact on brand awareness and customer behavior. This study analyzes the effect of celebrity endorsement on customer’s attitude toward brand as well as the effect of customer’s attitude toward brand on customer’s purchase intention in Vietnam. A survey was conducted with 306 individuals in Vietnam. After conducting the explanatory factor analysis (EFA), and multi-variable regression analysis, results indicate that customer’s attitude toward brand is positively affected by 03 factors: celebrity match-up congruence with the brand/product, celebrity trustworthiness, and celebrity expertise. Attitude toward brand also has a positive impact on customer’s purchase intention.

- Head and spine injury, along with the long-term effects of concussion of football players, is a very controversial health issue. As a result, the news has been covering this health issue, with many headlines involving famous NFL players. It has been assumed that this has made most Americans that follow football more aware of the risks involved in playing the game. However, we have not seen a decline in the number of young boys, ages 8-10, that are joining football leagues. For this age group to take part in playing football, these young boys need to have the permission of a parent or guardian to play, which demonstrates the adults support to their participation. Given the risks to these young boy’s health, we wonder why would parents allow or even encourage their children to play football? Using what you know about qualitative research, briefly explain (one page): How would you design a qualitative research study, with the goal of gaining an understanding of why parents allow their…arrow_forwardDo waiters or waitresses earn larger tips To answer this Do waiters or waitresses earn larger tips?

Use the following to complete them.arrow_forwardA study by University of Minnesota economist, Joel Waldfogel, estimated the difference in the actual monetary value of gifts received and how much the recipients would have been willing to pay to buy them on their own. The study suggested that the average recipient’s valuation was approximately 90% of the actual purchase price. a. In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss? Enter your answer to the cent. b. In 2017, approximately 250 million people in the United States were above the age of 18.
