We observe the difference of means D $=500$ for mean$($price$)$ of single room room rental apartments between $10$th floor Manhattan apartments and $1$ floor Manhattan apartments $.$ We run $10000$ permutation tests and we get the following results

Dnull$<200$ for $7500$ permutations

Dnull $>550$ for $200$ permutations

What are the tightest bounds we can derive for the p value of one tied hypothesis that mean prices of single room apartments in on the $10$th floor in Manhattan and single room apartments of $1$ floor apartments in Manhattan
