Having completed this project notebook, you will have hands-on experience: sampling and calculating probabilities from a normal distribution; the correct way to estimate the standard deviation of a population (the population parameter) from a sample; what a sampling distribution is and how the Central Limit Theorem applies; how to calculate critical values and confidence intervals; performing inference using such data to answer business questions, forming a hypthesis and framing the null and alternative hypothesis, and testing thsi using a t-test.
