The 25th percentile corresponds to z ≈ -0.67.
The 90th percentile corresponds to z ≈ 1.28.
So, you can write two equations in μ and σ as here:
.. μ -0.67σ = 10
.. μ +1.28σ = 20
The solution is
.. μ ≈ 13.45
.. σ ≈ 5.11
The expectation would be that the player would not get much money. 3, 4, 5, 6, 8, 9, 10, and 11 does not get a lot due to the entrance fee of $3. 20 - 3 = 17. 5 - 3 = 2.

The <em>correct answer</em> is:
The mean for July is smaller than the median; and
the mean for August is larger than the median.
Explanation:
A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.
Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.
The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.
The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.
