Suppose you want to know the variance of the weights of the only five iguanas in a particular zoo. You measure their weights to be 8.3, 8.4, 8.6, 9.2, and 9.5 pounds (15 points) What was different between the population variance and the sample variance? Which is bigger? Why is there a need to have a different formula? Write at least five good sentences in answering this question. (3 points) The population standard deviation is the square root of the population variance. Calculate the population standard deviation using part (c): (3 points) The sample standard deviation is the square root of the sample variance. Calculate the sample standard deviation using part (d): __________ (15 points) What is the difference between the population standard deviation and the sample standard deviation? When do you use each one? Write at least five good sentences in answering this question. (17 points) What did you do differently between calculating the variance and the standard deviation? What does each measure? Write at least five good sentences in answering this question.

Data from a random sample of 11 gravid female iguanas, including their postpartum weights and the number of eggs each produced, were collected. (1): Construct a two-way scatter plot for “female mass” against the “number of eggs” and on a separate graph construct a two-way scatter plot for “female mass” against log of the “number of eggs”. Looking at the two graphs you plotted, explain as to which of these two do you consider to be closest to a linear...

Suppose we are interested in analyzing the weights of NFL players. We know that on average, NFL players weigh 247 pounds with a population standard deviation of 47 pounds. Suppose we take a sample of 30 new players and we find that the average weight from that sample is 237 pounds. We are interested in seeing if the weight of NFL players is decreasing. Show work. What is the standard error? What is the margin of error at 90% confidence?...
