Consider a Situation in Which We Expect One-Third of the Observed

Consider a situation in which we expect one-third of the observed values to be in each of three categories. We can use an χ² goodness-of-fit test to test whether the frequencies of offspring are as expected. If the numbers of values in each category are 14, 19, and 27, what is the χ² value we would obtain?

A) 2.05
B) 2.13
C) 4.30
D) 4.39
