Eclosion refers to the emergence of an adult insect from an egg. The following data gives eclosion rates when nymphs were exposed to heat for various durations.

Duration (d)	0	1	2	3	5	10	15
Sample size	126	42	47	44	46	42	10
# Emerged:	107	38	44	40	38	35	7

Carry out a chi-squared test to decide whether it is plausible that eclosion rate does not depend on exposure duration.
a. State the appropriate hypotheses.

b. Calculate the test statistic value. (X^2)

For the bird egg length data set, conduct an appropriate test to determine if bird egg length differs among species. Assume that before you conducted this test you hypothesized about 3 contrasts a priori. These were that (1) Meadow Pipits, Wagtails, and Robins would be different than the other 3 bird species, (2) Hedge Sparrows would differ from Wrens, and (3) Tree Pipits would be different than all other birds. Use the approach we outlined in class to evaluate these...

If the egg-to-adult survival rates of genotypes A1A1, A1A2, and A2A2 are 90 percent, 85 percent, and 75 percent, and their fecundities are 50, 55, and 70 eggs per female, respectively, what are the absolute fitnesses (W) of these genotypes? Using A1A1 as the fitness reference, what are the relative fitnesses (w)? If the frequency of the A2 allele is p = 0.5, what will be its frequency one generation later? What will be the allele frequency when the population...
