Statistical Analysis of Download Speeds: MAT10251 Project

This document presents a comprehensive statistical analysis project focused on internet download and upload speeds, likely conducted as part of a statistics course. The analysis begins with estimating the proportion of time download speeds meet or exceed a certain threshold (40 Mbps), using confidence intervals. It then investigates whether the mean evening download speed surpasses a specified value (41 Mbps) through hypothesis testing. Further, the project examines the difference in download speeds between two speed tests using paired t-tests. Simple linear regression is employed to explore the relationship between download and upload speeds, quantifying the impact of download speed on upload speed. Finally, multiple regression analysis incorporates the factor of evening time to assess its influence on upload speed, and the best-fit model is identified based on statistical significance.
