Question

how people travel to work by region (estimated in millions)
us geographic region drove or carpooled public transportation total
northeast 20 4 24
midwest 28 1 29
south 47 1 48
west 28 1 29
total 123 7 130
the table shows data from the u.s. census bureau regarding the methods people use to travel to work categorized by geographic region. all the data is estimated in millions of people. based on the information in the table, what is the relative frequency of people in the northeast region who take public transportation?

Explanation:

Step1: Identify the formula for relative frequency

Relative frequency = \(\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\)

Step2: Identify the number of favorable outcomes and total number of outcomes

The number of people in the Northeast region who take public transportation is \(4\) million (favorable outcomes). The total number of people in the Northeast region is \(24\) million (total outcomes).

Step3: Calculate the relative frequency

Relative frequency \(=\frac{4}{24}=\frac{1}{6}\approx0.167\)

Answer:

\(\frac{1}{6}\) (or approximately \(0.167\))
