The Mars/M&M’s company claims that the proportions of the colors of M&M’s are the same for all colors. The colors are orange, blue, red, brown, yellow and green. Imagine in a sample of 100 candies, you get 24 blue. 1. What is your null and alternative? a. H0: p = 0.24, H1: p ≠ 0.24 b. H0: p = 0.167, H1: p ≠ 0.24 c. H0: p = 0.24, H1: p ≠ 0.167 d. H0: p = 0.167, H1: p...

34. Consider a firm producing and selling joint products produced in variable proportions in two competitive markets. For a given level of TC (or a level TR), the profit-maximizing combination of QA and QB requires _______, where PA = price of A, PB = price of B, CA = cost of A and CB = cost of B. MC of A and B can be used for CA and CB. A. P_A/C_A =P_B/C_B B. P_A/C_B =P_B/C_A C. P_A/C_A -P_B/C_B =1....

Suppose a firm has a fixed-proportions production function, in which one unit of output is produced using two workers and one unit of capital. a. Draw the isoquants for this production function, representing labor on the x-axis and capital on the y-axis. b.Define and show the expansion path of the firm. c. Suppose capital is fixed at three units. Show, by means of a line on the diagram, the short run possibilities of combining workers and capital when workers go...

1. Mourning doves have a small patch of iridescent feathers. The color is produced by a 330-nm-thick layer of keratin (n = 1.56) with air on both sides that is found around the edge of the feather barbules. Part A) For what wavelength or wavelengths in the visible spectrum would this structure produce constructive interference? 2. One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small...

Yellow coat color in guinea pigs is produced by the homozygous genotype, YY, and white is produced by the homozygous genotype, yy. One homozygous yellow guinea pig crosses with a homozygous white guinea pig to produce cream guinea pigs. a. What pattern of inheritance does this follow (complete, incomplete or co-dominance)? How do you know? b. Draw a Punnett square for a cross between two cream guinea pigs. What are the genotypic and phenotypic ratios?

GOODNESS OF FIT WORKSHEET The following is a quote from the Mars Company, maker of M&M candies: We can assure you that the colors are blended mechanically according to the formula. Our present means of color dispensing should place a fairly uniform blend of colors in every package; however, occasionally an unusual assortment of colors may appear. The theoretical percentages of each color (as given by the M&M company) are: Red Yellow Green Orange Blue Brown Plain 13% 14% 16%...
