i already solve stpe1,2 , so help me to do 3

matrix with 15*15

use one of this function

the solution should be like :

for variable : hours, salary, experience

for variables: hours,experience and salary

Question1 [5 Marks) A Human Resource Department of a company recorded data of seven (7) randomly selected employees as below: Name Salary Hours 9 6 4 7 10 7 11 16 12 Experi- ence 3 2 3 2 4 6 4 2 5 4 Ada Bob Charlie David Ello Fring George Alice John Pablo Richard Michael Leonardo Julia Jennyfer 5 8 5 3 8 15 10 4 8 15 5 4 2 7 16 9 15 11 13 15 3 6 5 5 7 8 1) Draw the boxplot of the variable "Hours". [1.5 Marks) 2) Which graph could show if Salary and Experience are correlated? Draw it and answer to the question: is there correlation between Salary and Experience? Explain. [1.5 Marks) 3) Create the distance matrix: choose a method and justify your choice. Who are the employees the most similar? [2 Marks) Note: write all calculations steps.
