Some MPs believe that there is a causal relationship between earnings and years of schooling. They show you an estimate of the impact of years of schooling on annual earnings: There are two groups of individuals – group 1 and group 2. Group 1 on average earns £60,000 per year with the average level of post-compulsory education of 6 years, while group 2 earns on average £40,000 with the average post-compulsory education of 4 years. The MPs conclude that the annual return to an additional year of education is 25% using the following equation [(£60,000-£40,000)/40,000]/(6-4)=25%. Ignoring time preferences and discounting, and if both groups face the same cost of schooling, you need to explain to the MPs why this is not a good estimate of the annual return to an additional year of education. Propose methods to the MPs to deal with the problem. (300 words)

- Three researchers are evaluating taste preferences among three leading brands of cola. After participants taste each brand, the first researcher simply checks to see if participants can distinguish them reliably by labeling each cola as "same" or "different" from the others, by giving them the same or different letter or number code. The second researcher asks each participant to identify the most preferred, the second most preferred, and the least preferred. The third researcher asks each participant to rate each of the colas on a 10-point scale, where a rating of 1 indicates “terrible taste” and 10 indicates “excellent taste," with the assumption that the difference betweeen a rating of 4 and 6 is the same as the difference between a 6 and 8. Identify the scale of measurement used by each researcher. nominal; ordinal; interval interval; ordinal; nominal nominal; interval; ordinal ordinal; interval; ratioarrow_forward“In the United States more than 50 firms produce textiles, but only 3 produce automobiles.

Suppose that you are hired by a state to estimate the effect of corporate tax rates on, say, the growth in per capita gross state product (GSP).(i) What kind of data would you need to collect to undertake a statistical analysis?(ii) Is it feasible to do a controlled experiment? What would be required?(iii) Is a correlation analysis between GSP growth and tax rates likely to be convincing?

- 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.?arrow_forwardRecently 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_forwardWhat are the main models for analyzing quasi-experiment data?

- 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?

Knowing that health-care facilities on Gozo were inadequate to deal with the complications of such a birth, she and her husband went to St. Mary’s Hospital in Manchester, England, to have the babies delivered. The infants, known as Mary and Jodie, were joined at the lower abdomen. Their spines were fused, and they had one heart and one pair of lungs between them. Jodie, the stronger one, was providing blood for her sister. No one knows how many sets of conjoined twins are born each year, but the number has been estimated at 200. Most die shortly after birth, but some conjoined twins do well. They grow to adulthood and marry and have children themselves. But the outlook for Mary and Jodie was grim. The doctors said that without intervention the girls would die within six months. The only hope was an operation to separate them. This would save Jodie, but…arrow_forward
