Many exoplanets that we have found are ”hot Jupiters” meaning that they are the size of Jupiter or larger, but orbit closer to their host star. The leading theory is that these planets formed in the outer parts of their solar systems, where hydrogen would have been able to condense, and then migrated in closer to their host star. Suppose that Jupiter were moved to the location of the Mercury (r “ 0.39 AU). Would Jupiter be able to retain its hydrogen-rich atmosphere? For Jupiter A “ 0.51, M “ 318MÀ, R “ 11.2RÀ.

Imagine you're in charge of a project aimed at discovering exoplanets that have the highest chances of supporting complex life forms. Use the Milky Way Habitability Explorer and the Circumstellar Habitable Zone Simulator to provide a rational for where in the Milky Way you would look for these exoplanets and what criteria you would look for. Be sure to consider each of the following: •Existential threats to planets. •Availability of planet-building materials. •Size of the CHZ. •Amount of time spend...

A test for a certain disease is found to be 95% accurate, meaning that it will correctly diagnose the disease in 95 out of 100 people who have the ailment. The test is also 95% accurate for a negative result, meaning that it will correctly exclude the disease in 95 out of 100 people who do not have the ailment. For a certain segment of the population, the incidence of the disease is 4%. (1) If a person tests positive,...

Many goods that we consume today could be made by slaves. These goods can be found in common products and components that are sourced from countries around the world. This means that many of us are inadvertently supporting exploitative labor practices. What role can consumers play to ensure that we don’t support factories and production facilities that exploit workers? What can businesses do to support fair and ethical supply chains? Are consumers and businesses doing enough? Word count must meet...

Many mortgage companies have included in their mortgage contracts the right to non-judicial foreclosure, meaning that if a mortgagee becomes delinquent under the terms of the note, the mortgage company can foreclose on the property without having to sue the mortgagee and obtain a judgment for judicial foreclosure. Do you think this nonjudicial foreclosure provision is fair? Is it good for the economy/business? Should it be allowed? Why or why not? Please remember to comment upon at least two other...

We have a random sample of size 10 from a normal distribution. We wish to estimate the population mean. Damjan suggests taking the average of the sample minimum and sample maximum. Allan thinks this will be a poor estimator and says we should use the sample mean instead. Do a simulation in R to compare these two estimators in terms of their bias and variance. Include a side-by-side boxplot that compares their sampling distributions.

1. When we conduct hypothesis testing with proportions, we have a sample size, n, and a number of successes, x. We compare our sample information to a previously collected population proportion and perform a hypothesis test to determine whether to retain or reject the null hypothesis. Suppose we collect n = 100 data points and find that of the 100 people sampled, x = 15 are left handed. We are then asked to perform a hypothesis test to determine whether...
