Gender is a 100-by-1 categorical array with two categories, Female and Male.
Use the categorical array, Gender, to access Weight and Height data for each gender
separately.
X1 = Weight(Gender=='Female');
Y1 = Height(Gender=='Female');
X2 = Weight(Gender=='Male');
Y2 = Height(Gender=='Male');
X1 and Y1 are 53-by-1 numeric arrays containing data from the female patients.
X2 and Y2 are 47-by-1 numeric arrays containing data from the male patients.
Create a scatter plot of height vs. weight. Indicate data from the female patients with a
circle and data from the male patients with a cross.
