Separate multiple modes with commas, if necessary. Previous Step Answers Selecting an option will display any text boxes needed to complete your answer.   No Mode Unimodal  Bimodal Multimodal

The migration pattern of Monarch butterflies are tracked by a catch-and-release method in which individual butterflies are tagged with a circular, lightweight sticker placed carefully on the wings so as not to impede their ability to fly. The sticker contains a unique ID number. Volunteers across the U.S. and South America capture the butterflies, record the IDs if they are tagged, and release them. This allows us to track the locations each unique ID is found, allowing us to estimate the migration pattern. On average, 1 out of 100 captured butterflies are already tagged. Suppose you are a volunteer and capture 50 butterflies; let X denote the number of those that are already tagged. What is the distribution of X? What is the probability that you catch at least one tagged butterfly?

A statistics instructor wonders whether significant differences exist in her students' final exam scores in her three different sections. She randomly selects the scores from 10 students in each section.A portion of the data is shown in the accompanying table. Assume exam scores are normally distributed.

Smoking History                             CoVID-19 Severity                                                 Low                                 High Current 87 15 Former 43 9 Never 136 64 4.) One research question that could be posed using the available data: “Is there an advantage to being a Never smoker when it comes to CoVID-19 severity?” Essentially, we would like to know if the rate of High CoVID-19 severity is lower for Never smokers than it is for Current/Former smokers. Determine a method that would be appropriate for answering this research question. Using StatCrunch* and the available data, perform the statistical procedure deemed appropriate. Hint: In order to adequately answer this question, you will need to perform an additional statistical procedure a. What method did you use to answer the research question e.g., One-Sample t-Test for Means? b. Why did you select this particular method to answer the research question? c. In one to two complete sentences,…
