Develop a monthly weather chart for the upcoming year listing average expected high and low temperatures, Math homework help

I have this project for math which I don't really understand I have to make a presentation that shows the charts and the scatterplots of the data from the last year along with the regression equations that you found that model this data

Goal:

Your task is to develop a monthly weather chart for the upcoming year listing average expected high and low temperatures.

Role:

You are the meteorologist at the local TV station.

Audience:

Website viewers looking for information on typical high and low temperatures  

Situation:

You should choose a city in which you would like to reside and look up the average high temperatures and the average low temperatures for the last year.   Use this information to find the sinusoidal regression equation and create an expected high and low temperature chart for each month of the coming year.  

Product or Performance:

You are to develop a presentation that shows the charts and the scatterplots of the data from the last year along with the regression equations that you found that model this data. Include a description, based on the regression equations, of the amplitude and period of the models. The presentation should also include the new high and low temperature charts that you have created based on your regression equation.

Standards for Success:

Your presentation should include the following:

• the original temperature charts, including the source of the information
• Scatterplots of both sets of temperatures should be included
• the two regression equations
• the new temperature charts that could be posted to the station's website
• charts should be completely labeled
• presentation should be presented in a clear, detailed, and organized manner
