5.8. Python skills check

Here we will recap the main bibts of Python you encountered this week

Set up Python libraries

As usual, run the code cell below to import the relevant Python libraries

# Set-up Python libraries - you need to run this but you don't need to change it
import numpy as np
import matplotlib.pyplot as plt
import scipy.stats as stats
import pandas 
import seaborn as sns
sns.set_theme() # use pretty defaults

Exercises

# 1. Draw a random sample from a binomial distriubtion with n=27 and p=0.4
k = # your code here
print('k = ' + str(k))

  Cell In[2], line 2
    k = # your code here
        ^
SyntaxError: invalid syntax

# 2. For a binomial distribution k~B(100,0.8), find the probability that k<=70

0.011248978720991624

The answer should be 0.0112

# 3. For a normal distribution x~N(80,4) find the probability that x<=70.5

0.00877447509573836

The answer should be 0.00877

# 4a. Make a for loop to draw 150 random samples from the distribution k~B(12,0.3) 

# 4b. Plot the values of k on a histogram
