Pregnancies Most pregnancies result in live births, butsome end in miscarriages or stillbirths. A June 2001National Vital Statistics Report examined those outcomesin the United States during 1997, broken down by theage of the mother. The table shows counts consistentwith that report. Is there evidence that the distributionof outcomes is not the same for these age groups? OutcomeLive Births Fetal Losses Age ofMotherUnder 20 49 1320–29 201 4130–34 88 2135 or over 49 21
B. Juries A social psychologist suspects that people who serve on juries tend to be much older than people in the general population. The psychologist obtains voter registration records and finds that 20% of registered voters are between the ages of 18 to 29 years, 45% are between 30 to 49 years, and 35% are age 50 or older. Next the psychologist monitors jury composition over several weeks and observes the following distribution of ages for actual jury members. Jurors' Ages Frequency 18 to 29 years 30 to 49 years 50 and older 12 36 32 What analysis should you conduct to determine if the composition of juries reflects the age distribution among registered voters?

In a computer game, different units are created randomly with different levels of range and Aggression according to the table below. Range is how far the unit can attack without moving, and Aggression is used to determine how far a unit will move to attack without direct command.
