- Table 1 reports the estimates of the effects of personal characteristics on a monthly wage. The variable birth order measures order of birth, i.e. 1st child, 2nd child etc. The total variation in monthly wage is 138787905. Use this table to answer the following questions: a) In column 6, are the effects of being black, living in the south, and living in metropolitan jointly important variables in determining monthly wage? (Hint: You can use R² to test this hypothesis). b) In column 5, are the effects of being black and living in the south jointly important variables in determining monthly wage? (Hint You can use R² to test this hypothesis). c) Do explanatory (independent) variables in column 6 jointly explain monthly wages?

Statistical properties of flow data for tributaries A and B indicate that tributary A has a yearly discharge rate smaller than its mean flow rate (?̅?) in 50% of the years while tributary B has a yearly discharge rate smaller than its mean flow rate (?̅?) in 60% of the time. In 70% of the years in which tributary A has a discharge rate smaller than its mean discharge rate (?̅?), tributary B also has a discharge rate smaller than its mean discharge rate (?̅?). Compute the probability that (i) both tributaries have a discharge rate smaller than their mean discharge rates, (ii) at least one tributary has a discharge rate smaller than its mean discharge rate, (iii) tributary A has a discharge rate smaller than its mean discharge rate given that tributary B has a discharge rate smaller than its mean discharge rate, (iv) at least one tributary has discharge rate higher than its mean discharge rate, and (v) probability…arrow_forwardThe number of interal disk drives (in million) made at a plant in Taiwan during the past 5 years follows: Year Disk drives 1 142 2 156 3 184 4 204 5 210 a) Using simple linear regression the forecast for the number of disk drives to be made next year= [__] disk drives (round your response to one decimal place)arrow_forward
