```python
|
|
import numpy as np
|
|
import matplotlib.pyplot as plt
|
|
|
|
# Fixing random state for reproducibility
|
|
np.random.seed(19680801)
|
|
|
|
mu, sigma = 100, 15
|
|
x = mu + sigma * np.random.randn(10000)
|
|
|
|
# the histogram of the data
|
|
n, bins, patches = plt.hist(x, 50, density=True, facecolor='g', alpha=0.75)
|
|
|
|
|
|
plt.xlabel('Smarts')
|
|
plt.ylabel('Probability')
|
|
plt.title('Histogram of IQ')
|
|
plt.text(60, .025, r'$\mu=100,\ \sigma=15$')
|
|
plt.axis([40, 160, 0, 0.03])
|
|
plt.grid(True)
|
|
plt.show()
|
