Question

A major car manufacturer was interested in whether its midsize car was selling consistently in two markets with respect to the annual income of the car purchasers.Five-hundred new car buyers in Chicago and Miami were surveyed.In Chicago,the following pattern was observed: < $20,000 5%;$20,000-$29,999 0%;$30,000-$39,999 40%;$40,000-$49,999 30%;≥ $50,000 5%.Among those surveyed in Miami,20 earned under $20,000;70 earned between $20,000 and $30,000;265 earned between $30,000 and $40,000;125 earned between $40,000 and $50,000;and 20 earned more than $50,000.Using the data provided,the calculated value of |2 =
A)0.883
B)36.30

The question seems to refer to a statistical test, likely a chi-square test given the context of comparing distributions across two groups. However, without specifying the exact formula or test being referred to by "|2", it's challenging to provide a detailed explanation. The correct answer likely involves calculating the differences in proportions or counts between the two groups across the income categories and applying a statistical formula that would yield a chi-square statistic, which is often used to compare observed frequencies with expected frequencies in categorical data. The value of 36.30 suggests a significant difference between the two groups' income distributions, assuming this value is a chi-square statistic.
