Note that most data analysis functions must be loaded from the add-on package Statistics`DescriptiveStatistics`, but the standard procedures, such as calculating the average, minimum or maximum values of a data set are built in. The plusminus sign is typed Esc - +- - Esc. Superscripts are typed Ctrl-6. Ignore the Null statement.

In[61]:=

... uot;, ,, Abs[Dt[V[r]]]/.{rrad, Dt[r] dr}, ,, RowBox[{ cm ., Cell[]}]}], ]}]}]}]

3 The volume of the sphere is 7178.08 ± 1.67552 Abs[rad]^2 cm .

Out[61]=

Null^5

This result would round off to 7200±300cm^3.

RowBox[{(*2*), , RowBox[{m[b_, w_] = 3 * b/w ;, , b_av = 100 ; db = 5 ;,  ... t[b] db, ww_av, Dt[w] dw}, ,, RowBox[{".", Cell[]}]}], ]}]}]}]

The number of monkeys is 41 ± 9 .
