addition rule - a mathematical rule used to calculate the probability of the union of events alpha - The probability of rejecting the null hypothesis when, in reality, it is true. Alternative hypothesis - Designated H1, this hypothesis represents the opposite of the null hypothesis and holds true if the null hypothesis is found to be false. The alternative hypothesis always states the population parameter is <, not equal (=/), or > a specific value. bar chart - A chart that displays q...

According to the Central Limit Theorem, what is normal? - ANS x̄ What are 2 reasons why we sample? - ANS - difficult to survey an entire population, if not impossible - expensive to survey entire population In a standard normal distribution, the mean is equal to ___ - ANS 0 In a standard normal distribution, the variance is equal to ___ - ANS 1 State the Central Limit Theorem - ANS X ~ unknown distribution(μ,σ²) If n→∞, then x̄ ~ N(μ,σ²/n)

This document contains my lecture notes of lecture 1 till 4 and 7 till 10. The course, Research Project, is taught by Adam Booij and Casper Troost at the University of Amsterdam in the first year of Economics and Business Economics. Since our lecturer stated that the exam will only contain questions about the material covered in lecture 1 till 4 and 7 till 10, this document is a summary of EVERYTHING you need to know to pass this course!
