DATA 606 LAB 4
In this lab we’ll investigate the probability distribution that is most central to statistics: the normal distribution. If we are confident that our data are nearly normal, that opens the door to many powerful statistical methods. Here we’ll use the graphical tools of R to assess the normality of our data and also learn how to generate random...

In this lab, we investigate the ways in which the statistics from a random sample of data can serve as point estimates for population parameters. We’re interested in formulating a sampling distribution of our estimate in order to learn about the properties of the estimate, such as its distribution. The data We consider real estate data from th...

Overview Given above table we can see different Airlines, City and the count of flight ontime and delayed. Analysis below shows, total number of flight delays between Airlines, Total number of flight delays between cities and the delay ratio between different city. [Note: Flight Delay percent = (Number of flight delayed / Total number of flight) ...
