"We Wear the Mask" is a poem written in 1895 by the African-American poet and novelist Paul Laurence Dunbar (1872-1906). The poem reflects the experience of being black in America following the Civil War. Black Americans continued to experience intense racism and hardship during this period. Read this excerpt from the poem and answer the question that follows: We wear the mask that grins and lies,It hides our cheeks and shades our eyes, —This debt we pay to human guile;With torn and bleeding hearts we smile,And mouth with myriad subtleties. Why should the world be over-wise,In counting all our tears and sighs?Nay, let them only see us, whileWe wear the mask. We smile, but, O great Christ, our criesTo thee from tortured souls arise.We sing, but oh the clay is vileBeneath our feet, and long the mile;But let the world dream otherwise,We wear the mask! What effect does the poet achieve by repeating the phrase "We wear the mask"…Atlantic hurricanes form off the western coast of Africa. As warm moist air rises, it begins to rotate around a low- pressure system. This rotation is sustained by warm ocean temperatures and a central low pressure. Once a sustained wind speed of 74 miles per hour is reached, the storm is considered a hurricane. As man-made climate change continues to increase the temperature of the Earth's oceans, it is expected that the strength of hurricanes will Typically, a lower central pressure within a hurricane's eye is associated with a higher wind speed. Here, statistical software (R/RStudio) will be used to explore this relationship by applying linear regression methods. Using a database of landfalling hurricanes in the United States, a linear regression will be used to correlate the central pressure of each hurricane to its maximum sustained wind speed. increase.

- Read the following problem description then choose the correct null and alternative hypothesis. A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 1 in every one thousand.A company has 30 employees, including a director. The lowest salary among the 30 employees is $22,000. The director’s salary is $180,000, which is more than twice as much as anyone else’s salary. Decide for each of the following statements about the 30 salaries whether it is true, false, or you cannot tell on the basis of the information at hand. • The median salary is below $60,000.• The average salary is below $60,000.• If all salaries are increased by $1,000, that adds $1,000 to the average.• If the director’s salary is doubled, and all other salaries remain the same, that increases the average salary.• If the director’s salary is doubled, and all other salaries remain the same, that increases the median salary.• The standard deviation of the salaries is larger than $180,000Please help me better understand word problem. A researcher was investigating variables that might be associated with the academic performance of high school students. The data included the average Math SAS score of all high school seniors in the city that took the exam (labeled as the variable SAT-M), the average number of dollars per pupil spent on education by the city (labeled as the variable $Per Pupil), and the percentage of high school seniors in the city that took the exam (labeled as the variable %Taking). As part of the researcher's investigation, he ran the following multiple linear regression model as SAT-M=Beta0 + Beta1($Per Pupil) + Beta2(%Taking). This model was fit to the data using the method of least-squares, results shown inside of table within photo. Question: What's the 95% confidence interval for Beta1, (coefficient of variable $PerPupil). Then determine the interpretation for Beta2 (coefficient of %Taking variable).
