A sociologist is interested in the voting rates of males and females. Two hundred males and two hundred females are randomly sampled. Of these, seventy percent of males and sixty percent of females voted in the last election. Construct a 95% confidence interval around the difference in the proportion of men and women in the population who voted in the last election. Test the null hypothesis that, in the population, there is no difference in the proportion of men and...

What are the key differences in gametogenesis between females and males? What is the key step in spermatogenesis that allows for unlimited sperm production? This step is not present in oogenesis and therefore only a finite number of eggs could be produced. (0-5pts) Guidelines: You must include in your answer how the processes are similar and how they differ. What would health implications have the finite number of eggs present to the female? What organs are responsible for each gametogenesis?...
