Given the same specifications of Problem 1, consider this time you are building a primary index on SSN using B-tree. Calculate (i) the order p for the B-tree, (ii) the number of levels needed if blocks are approximately 69% full (round up for convenience), and (iii) the worst-case number of blocks needed to search for and retrieve a record from the file given its SSN value-using the B-tree you are estimating.
