A survey was conducted and asked: "Do you consider your health to be poor?" This was coded as 1 for "yes" and 0 for "no."The effect of age (in years) and sex (1 male, 0 = female) on the outcome was examined using logistic regression. Thefitted logistic model is:=logit(ô) = −0.544 + ß * sex + 0.0331 * age(a) What are the odds of responding "yes" for a female subject who is 60 years old?(b) What is the estimated odds ratio corresponding to the age variable? Interpret this estimate.(c) Suppose that, based on the data from the survey, the odds of responding "yes" for males are 3.79% greater than theodds for females, adjusting for age. What is the value of Â?(d) If we only wanted to assess the association between survey response (yes/no) and sex, what other method(s) (thatwe have learned in this class) could we have used (name at least one)? In your own words, explain why we cannotuse the same method(s) if we want to consider the effects of both sex and age on survey response.

Karr and Coats studied the effects of several chemicals on the growth of the German cockroach. the following table gives their data for the percent of the chemical ?-terpineol in the diet of 20% ?-terpineol. Percent ?-terpineol 1 10 25 Days to Adult Stage 129 113 115 A. On the basis of the data given in the table, find the best-fitting logarithmic function using least squares. State the square of the correlation coefficient. (Use 4 decimal places in your answer.)y(x) = r2 = B. Use this model to estimate the days to adult stage with a diet of 20% ?-terpineol. (Round to the nearest day.)When a 20% ?-terpineol, then there are days to adult stage.

QUESTION 7 In order to estimate the effect on wage of years of schooling, researcher B analysed the dataset that researcher A collected in the previous question. Researcher B considers the following regression equation, + ... +₁² log(income), =B+B₁₂educ; 0 where educ. is years of school of individual i and includes additional terms associated with other characteristics in the data set. When researcher B was i carefully examining omitted factors in the error term u , she realised that unobserved factors such as motivation and work ethic would increase the income i' i level and be positively correlated with the variable of interest educ. If researcher B's conjecture regarding the unobserved factors is correct, then: O a. O b. The OLS estimator would overestimate the effect on income of educ.. i O c.
