14. File asafellow.csv contains the data described in Example 3.7. There are 18 strata, defined by the cross-classification of variables awardyr and gender. (a) Calculate the sampling weight for each member of the sample. Is the sample exactly self-weighting? (b) Estimate the proportion of Fellows who work in academia. In 2020, approximately 48% of the population of ASA members worked in academia. Does your 95% CI include the value 0.48? (c) Estimate the proportion of Fellows who majored in mathematics as undergraduates, along with its standard error. Use the same method as in Example 3.4 to deal with the missing data.

3. Calculate the U-factor of the 2 by 4 stud wall shown above. The studs are 16 in. OC (off-center). There is 3.5 in. mineral fiber batt insulation (R-13) in the stud space. The inside finish is 0.5 in. gypsum wall board; the outside is finished with rigid foam insulating sheathing (R-4) and 0.5 in. by 8 in. wood bevel lapped siding. The insulated cavity occupies approximately 75% of the transmission area; the studs, plates, and sills occupy 21%; and the headers occupy 4%. Remember that 2 x 4 studs are actually 1½ x 3½. If the outside conditions are 20 F and 70% humidity while the inside conditions are 70 F and 50% humidity, where is the most likely location for condensation to form? 1. Outside surface 2. Wood bevel lapped siding 3. Sheathing (rigid foam insulation) 4. Mineral fiber batt insulation 5. Wood Stud 6. Gypsum Wallboard 7. Inside Surface
