The council of a regional town conducted a survey to determine how their workers usually travel to work.

The study found that 68% of workers travelled using their cars, 17% used public transport, 11% rode bicycles and 4% walked.

A local large employer ran a similar survey at her workplace, with 150 responses recorded. Below are the observed counts for each method of transportation used by the sampled workers:

Method of Transport Observed Count

Car 98

Public Transport 29

Bicycle 20

Walk 3

d)State the degrees of freedom and P-value.

e)Giveyour conclusion (use = 0.05) in the context of the question.
