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?

R Studio       library(poliscidata)       2. (Dataset: nes. Variables: dhsinvolv_message, polknow_combined.) Online political activism is a relatively new phenomenon. In recent years, online social networks like Facebook and Twitter have become part of our everyday experiences and, for many people, a forum for political news and debate. From your own personal experiences, you may have some impressions about who is likely to post political messages online, but our personal perspectives are bound to be limited and incomplete. Let's use the nes dataset to gain a better understanding of who uses social media to promote political ideas. Survey participants were asked whether they had posted a political message on Facebook or Twitter in the last 4 years and the dhsinvolv_message variable recorded their responses.        1. According to the nes dataset, roughly 20% of respondents indicated that they had posted a social media message about politics in the past 4 years. If the probability of an…

A research study was conducted to examine the impact of eating a high proteinbreakfast on adolescents’ performance during a physical education physical fit-ness test. Half of the subjects received a high protein breakfast and half weregiven a low protein breakfast. All of the adolescents, both male and female, weregiven a fitness test with high scores representing better performance.Load the data into a dataframe named FitnessData. The fitness scores will be contained in the Score vari-able of the data frame (FitnessData$Score). The gender (“Male” or “Female”)of each subject is contained in the Gender variable (FitnessData$Gender). Theprotein level (“High” or “Low”) of each subject’s breakfast is contained in theProtein variable (FitnessData$Protein).(a)  Use RStudio to compute and plot the difference in means. Fitness score means should berepresented on the y-axis and the breakfast protein level should be represented on the x-axis.(b)  Judging by the plot created in part (a), does…

How important is discrete mathematics for a Data analysis?

I'm needing help on question b (the last question). Thanks!

The article “State and Federal Data on COVID-19 Testing Don’t Match Up” by Meyer and Madrigal in May 2020 stated that Florida had reported conducting 700,000 coronavirus tests, yet the Centers for Disease Control and Prevention reported Florida had conducted 919,000. The difference between these reports is 219,000 tests. What is the difference between the number of tests Florida reported administering and the number the CDC reported the state-administered as a percent of the number of tests reported by Florida? Round your answer to the nearest hundredth of a percent.

The Excel file for this assignment contains a database with information about the tax assessment value assigned to medical office buildings in a city. The following is a list of the variables in the database: FloorArea: square feet of floor space Offices: number of offices in the building Entrances: number of customer entrances Age: age of the building (years) AssessedValue: tax assessment value (thousands of dollars) Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics. Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of FloorArea and AssessmentValue. Is FloorArea a significant predictor of AssessmentValue? Construct a scatter plot…
