Question
A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%.
To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt.
From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts.
Assume the conditions needed to conduct a one sample proportion test are satisfied.
The setup for the null and alternative hypothesis is as follows:
H : p = 0.40; H, :p < 0.40, which is a left-tailed test.
Compute the test statistic and p-value for this Hypothesis test using Excel and round your answers to 3 decimal places.
