One hundred draws, with replacement, were made at random from this
box:
1 1 2 3
The results were: 45 1 s, 23 2 s, and 32 3 s.
(a) What is the observed value for the number of 1 s drawn? The expected
value? The chance error? The standard error?
(b) What is the observed value for the number of 2 s drawn? The expected
value? The chance error? The standard error?
(c) What is the observed value for the number of 3 s drawn? The expected
value? The chance error? The standard error?
(d) What is the observed value for the sum of the numbers drawn? The
expected value? The chance error? The standard error?
