Is ultrasound a reliable method for determining the gender of an unborn baby? Consider the following data on 1000 births, which are consistent with summary values that appeared in the online Journal of Statistics Education (“New Approaches to Learning Probability in the First Statistics Course” [2001]):

Ultrasound Predicted Female Ultrasound Predicted Male Actual Gender Is Female 432 48 Actual Gender Is Male 130 390 Do you think that a prediction that a baby is male and a prediction that a baby is female are equally reliable? Explain, using the information in the table to calculate estimates of any probabilities that are relevant to your conclusion.
