Southern Cross University: MAT10251 Project Part B Analysis

This project, submitted for the MAT10251 Statistical Analysis course at Southern Cross University, presents a comprehensive statistical analysis. It begins with calculating a confidence interval to estimate the proportion of time download speeds meet a certain threshold. The project then proceeds to test the broadband service provider's claim about average evening download speeds using a one-sample t-test, and the accuracy of the download speed data is checked by comparing the results of two speed tests using an independent samples t-test. A simple linear regression model is used to explore the relationship between upload and download speeds. Finally, a multiple linear regression model is used to examine the combined effects of download speed and time of day on upload speed. The project includes detailed statistical outputs, interpretations, and a bibliography.
