The ratio of the probability of that is 3 : 6
Solution: We are given:
We need to find the z value corresponding to probability 0.84, in order to find the how much money almost 84% of gamblers spent at casino.
Using the standard normal table, we have:
Now we will use the z score formula to find the required amount:
approximately
Therefore, almost 84% of gamblers spent more than $720 amount of money at this casino.
