Sea turtles exhibit temperature-dependent sex determination, meaning that ambient temperatures control whether or not a developing turtle embryo will become male or female. The data table reflects the numbers of turtle offspring counted in Year 1 and Year 2 of a study. Male Female Year 1 180 20 Year 2 164 33 What type of test can scientists use to assess whether or not the ratio of male to female sea turtles is dependent upon the year? O ANOVA O Chi-square contingency O 2-sample t test O Chi-square goodness of fit

The following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…
