THIS QUESTION REQUIRES GREAT KNOWLEDGE OF THE SOFTWARE R STUDIOS (CODE) AND STATISTICS
Question 3. The probability that an individual commutes to work by car is 0.9. If ten neighbors are studied.
A- What is the probability that ten neighbors all commute by car? Calculate by hand. Also explain which probability distribution you choose and explain WHY you use that distribution.
B- What is the average number of neighbors who commute to work by car? Calculate by hand.
C- With the help of R, calculate the probability distribution of the number of neighbors who commute to work by car, and illustrate the distribution as a table and as a graph. "please show code used for this"
Explanation / Answer
A : (0.9)10
B. 10*0.9=9
C.
x=rbinom(1000,10,0.9)
d=table(x)
M= as.matrix(d)
M[,1]=M[,1]/1000
