Suppose the profit from 1000 plays of a poker machine is normally distributed with mean 3.7 and standard deviation 1.8 Be careful with this question you have to look at EVERY option and tick every option that is correct Which is correct if you want to work out if profit from 1000 plays is in the bottom 2.28% 10 Finish. O a. You can use the fact that the 2.28th percentile
Suppose the profit from 1000 plays of a poker
machine is
standard deviation 1.8
Be careful with this question you have to look at
EVERY option and tick every option that is correct
Which is correct if you want to work out if profit from
1000 plays is in the bottom 2.28%
10
Finish.
O a. You can use the fact that the 2.28th percentile
of the z distribution is -2
O b. A profit is in the bottom 2.28% if it is less than
-1.70
O c. A profit is in the bottom 2.28% if it is less than
0.10
Given that
Population mean=3.7
Standard deviation =1.8
For 2.28th Percentile we have to find which statements are correct:
a. You can use the fact that the 2.28th percentile of the z distribution is -2
b. A profit is in the bottom 2.28% if it is less than -1.70
c. A profit is in the bottom 2.28% if it is less than
