Estimating the Difference in Proportions Between Two Communities

This activity investigates the assumption that older individuals are more likely to vote Conservative compared to younger individuals. Based on survey data from two age groups, students will test whether there is a statistically significant difference in voting preference using a proportion-based hypothesis test. Additionally, a confidence interval will be calculated to estimate the magnitude of the difference in support for the Conservative party between people over and under 40.

Seat Belt Usage and Serious Injury Risk in Car Accidents' This statistical exercise examines whether wearing a seat belt significantly reduces the likelihood of serious injury in car accidents among children. Using data collected from hospital admissions, students will apply hypothesis testing to compare injury rates between two groups: those who were wearing seat belts and those who were not. The task involves clearly formulating null and alternative hypotheses, calculating relevant proportions and test statistics, and drawing conclusions based on a 5% significance level to determine if the observed difference in injury severity is statistically significant.
