- (2) 3.3 Instructions: Please answer these a.b.c questions. DO NOT use excel. Please explain well by your knowledge, written by yourself on a paper or else.QUESTION 9 Question: Consider the following Cost payoff table ($): $1 $2 53 14 6 D1 10 15 33 D2 25 12 22 D3 34 What is the value (S) of best decision alternative under Regret criteria?5
- Question 1: Use the following study (link here) to answer the following questions below: What are the independent and dependent variables of the study? b) Is this study experimental or observational? How can you tell? c) Is this study quantitative or qualitative? How can you tell? d) One of the primary end points/outcomes the study listed was the number of days that it took to reach a 50% reduction in symptoms as reported on a 12-Symptom scale. In Table 2, you can see that the statistical test they used to evaluate differences between groups for this end point produced a p-value of 0.97. Please provide an interpretation of this p-value, explaining what it means in terms of whether significant differences exist between the groups in the number of days it took to achieve a 50% reduction in symptoms on the 12-Symptom scale.QUESTION 3 What is the main limitation of this study? In 2009, investigators were interested in evaluating the relationship between physical activity and being overweight. Using BRFSS data, they found 100 participants in South Carolina. 69 of these participants were overweight, and the remaining 31 were not. The investigators found that 46 participants who were overweight reported low levels of physical activity. The investigators also determined that 22 participants who were not overweight reported high levels of physical activity. This type of study is expensive to carry out, and non-compliance of study participants must be dealt with in the analysis. The exposure and outcome were measured on study participants at the same time; therefore, temporality cannot be established. O The unit of observation is the group, so results cannot be assumed to apply to individuals. O The study only includes cases. There is no comparison group.1.

(b) What sort of chart would you recommend summarizing these results?Promoting population growth is an important policy of an anonymous country, and an equally important issue is to improve its people's health, both physically and spiritually. In relation to this, a problem of considerable interest to the country's health officials as well as to its ordinary people is to understand the effects of smoking during pregnancy on infant health. One typical and convenient measure of infant health is birth weight since a new-born infant who is too light can put the infant at risk for contracting various illnesses. Hence a simple linear regression (SLR) model could be proposed as follows: \[ \text { weight }=\beta_{0}+\beta_{1} \text { ciga }+e, \] (1p) where weight is birth weight in ounces and ciga is average number of cigarettes the mother smoked per day during pregnancy. Using the popular ordinary least squares (OLS) method and the relevant data from BabyWeight - a dataset on some relevant variables or factors compiled from a recently-conducted random survey…
