Hypothesis Testing

In statistics, there are two ways to calculate the sample data. One is descriptive statistics and the other is inferential statistics. In descriptive statistics, all of the information is defined through graphs and charts. In inferential statistics, it allows one to test the hypothesis and it is always used to predict the data. Inferential statistics has two main areas: estimating parameters and hypothesis testing. A hypothesis is a statement about the unknown parameter of the population which we want to verify from the information available from the sample. The premise may or may not be true. The estimation of the whole population would be a reasonable way of deciding if the statistical hypothesis is valid. There are two types of hypotheses. They are null hypothesis and alternative hypothesis.

2. You are interested in the effect of a factory being inspected on whether it reduces its pollution output. There's a variable "number of reported violations" that you have. When the number of reported violations goes from 9 to 10, the probability of being inspected jumps from 20% to 60%. Average pollution levels decrease from 600k Imetric tons of CO2 to 500k metric tons going from 9 to 10 violations as well. What is the fuzzy regression discontinuity estimate of the effect of inspections on air pollution levels?
