- Answer this pleaseMy topic is Hair Length, I need the solutions.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 marketing firm wishes to test the effectiveness of the audio/visual presenation of certain information as opposed to the purely audio presentation of information. To this end250 volunteers were given a 10 minute presentation in which the information was presented in an audio/visual format. A second group of 250 volunteers was presented the same information in a purely audio format. Each person in each of the two groups was asked the same 20 questions related to the infomrstion in the presentation. The audio/visual grouo had an average of 10.2 correct responses with a sample standard deviation of 4. The purely audio group had an average of 9.4 correct responses with a standard deviation of 3. The marketing firm believes this means that the audio /visual format leads to better retention of the information. We test the hypothesed H1: µ1 - µ2 = 0 versus Ha: µ1-µ>0 at a 2% level of significance. Here µ1 denotes the population average number of correct responses for individuals…I need help with just part c. Someone on here already answered it for me but I'm really confused as there are steps missing and I'm not sure what to put in the calculator.
