Hello,
I have this question that I dont know how to solve.
Generate the matrix “Customers” containing random values for the following variables. The matrix must contain 3000 people.
a. Gender. Must be either 1 or 0. 0 signifies that the person is female.
b. Age. Must be between 21 and 85.(I have tried using the same as randi(85,3000,21) but it gives me a matrix which is [3000,21] and i need it to be [3000,1] since there will only be 1 age per customer.
c. Insurance risk. Must be a value between 1 and 10. (This I have solved by using randi(10,3000,1))
Can anyone help me solve this please?
Thank you in advance

Customers.Gender = randi([0,1],3000,1);
Customers.Age = randi([21,85],3000,1);
Customers.Insurance_risk = randi(10,3000,1);
