"Analysis" is the singular noun; "analyses" is the plural. Since your object is plural ("NIH research activities"), the inference is that at least one "analysis" has been made of each single "NIH research activity", and thus there are many "analyses" of the "NIH research activities".
This is further borne out by the other subjects: "reports" and "data", both of which are plural ("data", though often used to describe a single piece of information, is the plural of "datum").
If you wanted to specify that, indeed, there was only one analysis made of all NIH research activities, you would say "reports, data, and an analysis of all NIH research activities", using an indefinite article to reinforce the singular.
