How to plot a matrix with a column matrix

Hello,

I have an assignment which i dont understand how to fix.

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.

c. Insurance risk. Must be a value between 1 and 10.

2. Create a plot that shows the distribution of the insurance risk for males

3. Create a plot that shows the distribution of males and females

I have completed all the above and gotten the distribution of both males and females:

Males: 1496 and female 1504.

But i dont know how to plot these to show the distribution.

Can anyone help me?

Thank you in advance.

Post your code

[Matrix-Matlab]

sum(male)

ans =

        1496

>> female = 3000-male

>> hist(customer_gender)

I then got a histogram that shows it. But now im struggling with this question:

Calculate the average insurance risk for males, females and combined. The averages must be rounded to two decimals.

Can you help me?

Okay I managed to solve it on my own

Assuming Customers is a structure array (could also be a table though), you could do this

% Extract all risks, regardless of gender, into one array:
allRisks = [Customers.insuranceRisk];
% Show the distribution in the current axes, creating one if one does not exist already:
histogram(allRisks);
