For this lab assignment you will need to write some code and create some graphs. You may use excel to create your graphs, or other language of your choice. Your data needs to demonstrate the experimental running time for Selection Sort (code in book), Merge Sort (code in book), and the Arrays.sort() method. Here is a basic outline of how you need to code this assignment. 1) Create several arrays of size 100, 1000, 10000, 100000, 1000000, … (you need...

Let x be the vector 1:366. Use a nested for loop to estimate, for each value of the vector x[i] = i, the corresponding probability y[i] that there will be at least one common birthday if there are i people in a room (ignore leap years, as usual). Your for loop should create a vector y of the same size as x. Now use the plot command plot(x,y) to draw the graph. Use google to see how to add some...

The following question can be answered in R code (using R-Studio or a program of your choice). Load the “star” data from the “faraway” package, and model “temp” using “light”. One may also suspect that the residuals (use all the data) follow a t distribution instead of normal. Using the same logic that we produced the QQ plot for comparing to the normal distribution, produce a QQ plot for comparing to a t distribution. You need to decide the degrees...
