INFERENTIAL STATISTICS

2. The researcher department of traffic and risk management conducted the study in controlling speed while
driving a vehicle and found out the key reasons to regulate and improve the traffic flow efficiency, and
reducing the risk of danger. The focus of the research is on the distance needed to fully stop a vehicle at
different speeds. Using the data given below, is there a significant relationship between speed and breaking
distance at alpha 0.05?

Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
