Part 3. (13 points) Simulation of Gamma Random Variables Background: When we use the probability density function to find probabilities for a random variable, we are using the density function as a model. This is a smooth curve, based on the shape of observed outcomes for the random variable. The observed distribution will be rough and may not follow the model exactly. The...

Please show your work with the formulas written out. Please answer as if you can not use a calculator, or only use a four function calculator (because that is how I have to learn it). Do not just put down the calculator keystrokes I need to see every step and number to learn how to do it. 17.

Create a new program in Mu and save it as ps3.4.1.py and take the code below and fix it as indicated in the comments: # Write a function called hide_and_seek. The function should # have no parameters and return no value; instead, when # called, it should just print the numbers from 1 through 10, # follow by the text "Ready or not, here I come!". Each # number and the message at the end should be on its own...
