The figure above represents the an experimental test of Lack’s Hypothesis.  The dark line represents the number of young that should survive from each clutch based on Lack’s predictions of optimal clutch size in birds.  The gold histogram represents the observed data demonstrating that birds rarely have the clutch size predicted. Explain why we see this difference between predicted and observed clutch sizes in birds even when abundant resources are available? This answer should have at least 1 full sentence.

Please examine the life table below, calculate the missing columns. These are coded as multiple fill in the blank values, lettered A – D. We will only accept a numerical response estimated to thousandths place (e.g., 0.500 would be acceptable, but not 0.5, 50%, px = 0.500, or point five). When calculating, round each calculation to this level of precision. The spaces to fill in with answers appear at the bottom of the question, A = ___, B = ____, etc.  Use this to help you :  Question A: What is the GRR for this species: __________Question B: What is the R0 for this species: ___________Question C: What is the total number of “Boomers” that survived to year n1? (purple box, second row of n1) ____________Question D: What is the total number of babies that could be born in year n2? (pink box box, first row n2)  _________Remember: You must consider how many of the cohort made it to the next year. In years n1 and n2 you also have individuals who can reproduce, so you must also consider how many babies those individuals can have. In some years, you may have more than one cohort that can reproduce at the same time, so don’t forget to add those up when considering # offspring. I’ve left the first two parts of the steps here for you to hopefully help jog your memory!

A retail store would like to calculate the response rate for the telephone survey that it conducted. Researchers for the retailer called 650 households. Respondents must have made a purchase from the retailer within the last two months to be eligible for the survey. There were 262 completed interviews, 68 refusals, 123 not-at-homes, 150 ineligibles, and 47 nonworking numbers. If the eligibility percentage was 64%, the response rate was _____.
