Restaurant spending example
Let's go back to the example of the restaurant chain that has been collecting data about customer spending. Recall that the data shows that the spending is approximately normally distributed, with a mean of 3.15 and a standard deviation of 1.5 per customer, as pictured in the plot.
We can use the already imported norm object from scipy.stats to answer several questions about customer spending at this restaurant chain.
