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.

A parent downloads an app that allows him to monitor the amount of screen time his child is using on the phone. The child claims that she is only using 1 hour per day on the phone on average, but the app, over the course of 47 days, finds that the child used an average of 1.2 hours per day. The parent wants to know if the child is using an average of 1 hour per day for all days of use. a) The 1.2 is a/an: variable population parameter sample statistic observational unit b) The sample size is: 1 47 1.2 c) Each day is a/an: population parameter observational unit variable sample statistic

A college professor conducted a survey in order to assess how much money nursing majors spend on course material compared to all other majors. To do so, she selected a random sample of 34 students. Each student was classified as a nursing major or as a non-nursing major. They were then asked how much they spent on books and other materials required for their courses this semester. Here are parallel boxplots summarizing the responses: Based upon the boxplots, which of the following statements cannot be concluded? (A) The range of the distribution of the cost of course materials for nursing majors is about the same as that of non-nursing majors. (B) The maximum cost for non-nursing majors is greater than the median cost for nursing majors. (C) The variability of the cost of course materials for the middle 50% of nursing majors is greater than the variability of the middle 50% for non-nursing majors. (D) The median cost of course materials for nursing majors is over $300 more than…
