20 = short
(a) What frequency of tall and short plants is expected?
(b) To test the goodness of fit between the observed and expected values, provide the needed statement of the null hypothesis.

(d) How many degrees of freedom are associated with this test of significance?
(a) 1:1 (25 tall and 25 short)
(b) The deviations from a 1:1 ratio (25 tall and 25 short) are due to chance.
(c) ?2 = 2
(d) 1
