Most Common mistakes from test. 4e and 6d4. In her promotional practices, a queen ant has been accused ofdiscriminating against ants with short antennae. During the preceding year,six workers were up for promotion. Four of them, with antenna lengths (inmm) of 65, 71, 72, and 73, were promoted. Two workers, with antennalengths of 63 and 68, were bypassed for promotion.

a. – d. List all the possible combination of antennae lengths and find averages, how likely is it to get an average of 65.5 or less?

e. Is the evidence of antenna length discrimination relatively strong or relatively weak? Justify your conclusion.

The other most common mistake from the test: 6d6. Refer to the situation described in Question 4: In the precedingyear, six workers were up for promotion. Four of them, with antennalengths (in mm) of 65, 71, 72, and 73, were promoted. Two workers,with antenna lengths of 63 and 68, were bypassed for promotion. a. List all possible pairs of antenna lengths for workers who might

have been bypassed for promotion.…d. Is the evidence of antenna length discrimination relatively strong

or relatively weak? Justify your conclusion.

On pg 16 under Discussion of Logic of Inference: 0.05 is considered unlikely and in a typical court case, there would have to be a probability of 0.25 or less for it to be considered a discrimination.
