- The sample mean.
- The sample size.
- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.
- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).

Step-by-step explanation:
Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.
It is given that 
Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event 
(D given M does not occur) is a null event, i.e
It is also given that,
Recall that : 
Here, we are required to find
