It is believed that number of people who attend a Mardi Gras parade each year depends on the temperature that day. A regression has been conducted on a sample of years where the temperature ranged from 28 to 64 degrees and the number of people attending ranged from 8400 to 14,600. The regression equation was found to be = 2378 + 191x. Which of the following is true?

A point charge Q_(1) = 20 μC is at (-d,0) while Q_(2) = -10 μC is at (+d,0). Take d = 1.0 m and x = y = 2 m. (a) Find the resultant field at a point with coordinates (x, y). (b) Besides infinity, at what point would the net field be zero? (c) What's the electric force on Q_(3) = -2 μC? (Ans: {(3.5 × 10^3 (hat(ı)) - 8.6 × 10^3 (hat(ȷ))) (N/C); x = 5.8 m; (-7 × 10^(-3) (hat(ı)) + 17.2 × 10^(-3) (hat(ȷ))) N)}

Problem 4.4 The following table gives the sums of squares (SS) from an analysis of variance of a random-breeding population of Drosophila melanogaster. The trait was the number of sternopleural bristles. There were 62 sires each mated to 3 dams. Each female laid eggs in one vial. The bristles of 10 female offspring of each dam were counted and the number of bristles is treated as a quantitative trait. Variation Df SS MS E(MS) Between Sires ____ 272.121 ____ $\sigma_{w}^{2} + \underline{\Box}\sigma_{d}^{2} + \underline{\Box}\sigma_{s}^{2}$ Between Dams ____ 255.564 ____ $\sigma_{w}^{2} + \underline{\Box}\sigma_{d}^{2}$ Between Sibs ____ 1494.882 ____ $\sigma_{w}^{2}$ (1) Complete the ANOVA table by filling up all the blank (underlined) spaces. (2) Calculate the variance components of sires ($\sigma_{s}^{2}$), dams ($\sigma_{d}^{2}$) and within family ($\sigma_{w}^{2}$). (3) Estimate the heritability using all the three formulas provided in the handout (paternal-half sib, maternal half-sib and full-sib). Note that the three estimated narrow sense heritability should be different.
